Mills compares his art to the
Beano comic strip and
Ken Loach's I, Daniel Blake. The exhibitions he creates are often humorous and political in nature, and he prefers positivity to anger. His sculptural work often includes interactive AR elements, and are sometimes inflatable. An
iPad is his primary tool, which he started using after reading an article on painter
David Hockney's usage. The tablet is portable and the high definition allows him to scale up his artworks. This has allowed Mills to regain some of his freedom. He has a free augmented reality app, Jason Residential, available to download from Google Play. Mills has also worked for the Wakefield Trinity Wildcats, a rugby team based in based in West Yorkshire, for a year long project. The two-hundred foot mural included portraits of star players and utilised 3,000 school children's drawings of themselves. It was installed around the stand of the stadium. His father and he would watch rugby together when he was a child and he has stated that it was the "closest time I ever spent with him". The piece, which is dedicated to his father, is designed to be a time capsule, and Mills hopes that the children featured will one day bring their own children to see it. In 2021, he created a statue called 'I Am Argonaut', for the Folkestone Triennial, an art festival held in Kent. The sculpture was placed opposite a statue of William Harvey, the local physician who, in 1628, discovered how the heart circulates blood around the body. 'I Am Argonaut' is depicted pointing at a hole in its chest, where the heart should be located, laughing; the statue of Harvey holds a disembodied heart. The piece was produced in conjunction with Shape Arts. Mills created other Argonaut installations as part of an
Arts Council England funded project 'Jason & his Argonauts on Tour' which toured the United Kingdom. The centrepiece was the 'Changing Places Argonaut', a 3.5 metre inflatable which "relates people's stories from the
Changing Places movement". In 2022 the
People's History Museum in
Manchester,
England exhibited 'The Manchester Argonaut', a sculpture about "activism and the rights of disabled people". == Awards ==
