These are some the pre-prod research to find a nice overall look.

At first I planned to do this short in 3d with a NPR render. On the high right corner you can see a simple 3d chicken model with a test of NPR render.  But I wasn't  satisfied by the overall look in 3d so I started to search something else.  I was experimenting with the vector paint tool of combustion when I found something nice.
