From a short distance Lenz's paintings appear to be photo realistic, but are made up of thousands of brushstrokes. Lenz starts a new painting by initially working out ideas in small pencil “thumbnail” drawings. The artist then photographs all the various elements of the image individually. These are used as the main reference material for the final painting. For a major work, he also completes an extensive array of color sketches. After the composition is fully developed, the image is drawn out carefully with pencil on a stretched canvas or board. Lenz's painting technique is quite traditional; straight oil paint is applied using small round sable brushes over a primed and warmly tinted linen canvas. Lenz's subjects are people who society has taken for granted, forgotten, or overlooked. These people are portrayed in an empathic way, and the extensive landscape surrounding the subjects describes their lives and the community beyond. Lenz incorporates various elements as metaphors to deepen the meaning of his images. Sometimes Lenz takes dramatic liberties with reality, and the use of metaphors occasionally drives the scene toward the surreal. One reoccurring theme in Lenz's work is that life's limits can be transcended with perseverance, personal heroism, and divine oversight. In “Sam and the Perfect World,” the hills of Wisconsin are a metaphor for a modern civil society that values perfection. Humankind has transformed the landscape for their own use, altering this Garden of Eden, and erected a barbed wire fence; separating Sam for the rest of the world. A halo around the sun is said to represent a deity looking down upon the handwork of humankind. Without idealization or sentimentality Lenz portrays his son with his red shirt and Oshkosh overalls to show he is like any other boy, and yet he is not. “Nevertheless,” the artist says, Sam has “something very important to say.” Lenz is influenced by the isolated figures of
Edward Hopper, the regionalist sensibility of
Grant Wood, and by the symbolic meaning infused in the people and objects of
Andrew Wyeth. The Outwin Boochever Portrait Competition first place award also entitled Lenz to paint a portrait of a remarkable American for the Smithsonian National Portrait Gallery's permanent collection. On May 9, 2009, the Gallery unveiled Lenz's historic portrait of
Eunice Kennedy Shriver, the first portrait the Gallery has ever commissioned of an individual who had not been a U.S. President or First Lady. The portrait depicts Mrs. Shriver with four
Special Olympics athletes and one
Best Buddies participant on the beach near her Cape Cod home. In the painting from left to right are Airika Straka (Special Olympics Wisconsin),
Katie Meade (Best Buddies Iowa), Andy Leonard (Special Olympics Ohio), Loretta Claiborne (Special Olympics Pennsylvania), Mrs. Shriver, and Marty Sheets (Special Olympics North Carolina). In 2010, his commission "Wishes in the Wind", depicting three disadvantaged
Milwaukee children blowing
soap bubbles, was hung in the
Wisconsin Governor's Mansion. In 2011, newly elected Wisconsin Governor
Scott Walker removed the painting and replaced it with a 140-year-old portrait of
Old Abe the War Eagle. She is the most famous of all Civil War
mascots. ==Awards==
