Career beginnings In 2011, Terrace was an assistant for a thesis
horror comedy film by Zach Bellissimo titled
Blanderstein, as was Terrace's roommate Luz Batista.
Blanderstein went on to win a Dusty Award for "Outstanding Traditional Animation and Achievement in Traditional Animation Character Design," tying with Michael Ruocco's thesis film,
Destiny is for the Birds. After graduating from SVA in 2013, she interned the following summer at
JibJab, where she met an individual from
Gravity Falls who saw her student film
Mirage and sent her a storyboard test, subsequently hiring her for
Disney Television Animation and landing her a job on the series as a storyboard revisionist. Terrace also animated sequences for the show that were animated in-house due to being considered too important to be animated by outside studios. In 2019, she said she had a "wonderful experience" on
Gravity Falls and said she "couldn't have asked for a better first gig."
The Owl House After years of working on other Disney Channel shows, Terrace developed the characters and "baseline idea" for an original series at the end of 2016 and pitched the series a few months after she started directing
DuckTales in 2017. The pitch, "a young girl goes to another world and learns magic from an older witch", later developed into
The Owl House. The first character she created was the Owl Lady, which she based on the women in her family, The series was also influenced by
Pokémon Red, a game Terrace's father, Thomas Terrace, an attorney in
Hamden, Connecticut, gave her before he died when she was age 11. The series was approved for a second season on November 21, 2019.
The Owl House has been praised for its depiction of an
LGBTQ+ relationship between the characters of
Luz Noceda and
Amity Blight, for which Terrace is responsible. During its second season, the series was also lauded for the inclusion of a
non-binary transgender character, in the form of Raine Whispers. She actively uses
Twitter to confirm the LGBTQ+ identities of characters. Although such portrayals garnered support from viewers and critics, Terrace noted that when the series was greenlit, certain Disney executives told her she could "NOT represent any form of bi or gay relationship on the [Disney] Channel" but that other executives later helped ensure this representation was within the show. Terrace told
Vanity Fair in March 2021 that she was open about plans for Luz to be bisexual and include LGBT+ characters during the development of the show. She was later told that she could not "have any kind of gay storyline among the main characters." Terrace said that, in response, "I let myself get mad, to absolutely blow up, and storm out of the room. Life is short and I don't have time for cowardice, I was ready to move on to greener pastures if need be." A "week or two" later, she was "given the all-clear" and describes the studio as supportive since then. On February 12, 2026, Terrace announced that Mikki Cristostomo and she are writing a graphic novel called
The Owl House: The Long-Lived King. It is scheduled to release on September 29, 2026.
Knights of Guinevere In March 2023, Terrace announced on her Instagram that she had left Disney. Afterwards, co-founder of
Glitch Productions Kevin Lerdwichagul contacted Terrace on social media, offering her to work for the studio, saying: "Do you want to make whatever you want?". She accepted the offer and it led to the creation of Knights of Guinevere.
The Michigan Daily said that her career in Disney influenced the pilot's plot, it noted that Park Planet (fictional corporation in the pilot) shared some similarities with
The Walt Disney Company. The pilot was described by Terrace, on social media, as different from
The Owl House, describing it as being "much more adult oriented" and having "adult themes," such as "animated blood and gore". The pilot premiered on September 19, 2025, with Terrace telling
Animation Magazine that the series is a "passion project" and she, Zach and John created "with some of the best artists, animators, musicians and production crew we know." In the first two days following its release on September 19, the series' pilot episode received eight million views and Evan Valentine of
ComicBook reported that in the five days after its release, it had garnered over ten million views. Terrace said that the pilot reminded her of a "collaborative student film" because she and others were "passionately working together" on it, with
TheWrap saying that the pilot received an "overwhelming positive response." On February 13, 2026, Glitch Productions announced
Knights of Guinevere had been greenlit for a full season.
Other work In 2017, Terrace directed various episodes of the
2017 DuckTales reboot and made the character
Webby Vanderquack "more dynamic." The line producer for the second season of
Gravity Falls was also working on
DuckTales and brought her into the show in spite of Terrace having never watched the
original series before working on the show, though she is a fan of the
Carl Barks/
Don Rosa comic books both series draw inspiration from. Also that year she worked as a storyboard revisionist for
Tangled: Before Ever After, directed by Tom Caulfield and Stephen Sandoval; Sandoval would later work on
The Owl House. She later storyboarded the fourth episode of ''
Rapunzel's Tangled Adventure'', "Challenge of the Brave." In 2018, she inked 34 pages of Hirsch's graphic novel,
Gravity Falls: Lost Legends: 4 All-New Adventures! In 2019, Terrace illustrated an alternative cover for issue 4 of
Adventure Time with Fionna and Cake: Card Wars, a
BOOM! Studios six-issue miniseries which featured
Fionna and Cake, the gender-swapped versions of
Finn and
Jake. Terrace also provided guest animation for the episode of
Adventure Time titled "
Bad Timing". In 2020, Terrace criticized the cancellation of
The Venture Bros. by
Adult Swim, writing "this timeline sucks." In 2021, the director of
The Mitchells vs. the Machines,
Mike Rianda, revealed that Terrace was a
storyboard artist for the film. The same year, Terrace provided rough animation for
The Owl House season 2 episodes "Keeping Up A-fear-ances", "Hunting Palismen", and "Eclipse Lake". From February 2, 2025, to March 9, 2025, Terrace had a solo art exhibit in
Alhambra, California which displayed a wide array of her artwork since 2015, in order to celebrate the release of an art book entitled
skin & bones and related merchandise. == Personal life ==
