This is just last year's study of my panda character. I've been trying to improve my characters anatomy, seems like they've been growing wider and taller, with a nice belly to boot.
But there was something always wrong, it was fine when the characters are sideways, but I noticed this problem I drew characters facing front and center view. Didn't know what it was.
Until this year and many studies of body references, the problem with the body was the chest or pecs. By the time I did the Fellow Shaman piece, this was resolved. In my observation,
it seems the pecs should be as big as the head. Well, that's just me.
