Caught this last night. It takes a whole 'nother level of skill to analyze the stylepoints- techniques and motifs of 100+ cartoonists and echo their style. Pretty amazing.
For his Mikenesses series- Adventure Time and Bravest Warriors cartoonist Mike Holmes drew himself (often accompanied by his cat Ella) in the styles of more than 100 different cartoonists and animators. It's a neat study of the styles–and it's also incredibly charming.
