Pierre Zenzius studied animation production at Gobelins. A recent demo reel of his varied work is embedded below:
Pierre has a knack for forcing perspective while drawing vehicles and the interiors of rooms, which you can see examples of on his 2012 portfolio site. Pierre also chooses vibrant colors and puts colors together unexpectedly. Looking at his work as one body you can see that his color combinations are something that unifies his work.
Also he draws these great tubular cloud shapes. See more from Pierre on his blog.
