awesome

I like them all, especially the line work on the unfinished one in upper left :D

Far right foxy, her neck might be too thin (can't tell if hair is occluding the neck or not?) and cheek could use some dimensional indicators, perhaps in the coloration, so it not look flats.

Bottom blue one has pretty good dimensionality though; his face is at a challenging angle and you doned pretty goods.

Unfinished upper left just looks HEAVENLY! xD

yeah the fox girl has hair on her neck its part of he mohawk the top unfinished one will be finished sometime soon
