We (classmates Chris Ricardo Pierre & Steeeve) spent a good part of May working on this tiny tiny mini-film for TAAFI with the prompt "Caught in the Act". The hardest bit (there were a lot of hard bits...) was keeping it under 19 seconds and still have it make sense.
I worked on uhhh a bit of everything... mainly art direction, layout, compositing (bleh!), animation for the mice with instruments, and lots and lots of inbetweening and cleanup.
Older layout: sorely tempted to make it black and white because black and white is gorgeous, but decided it was too Papermany and needed to learn more color theory anyway.
