This character sculpt is based on one of Tom Booth's works. I just found this character so darling, with all his bird pals. He was originally sculpted in A-pose, then retopologized, and then posed with Mixamo.

The original concept by artist Tom Booth! Just the sweetest style, you can find it on instagram here:
