Maybe its intentional but having the really dark purples on their face makes it hard to discern their facial features from far away.
Besides that, the legs are supposed to be like a wolfs right? I don't know much about wolf anatomy, but I feel like if you look closely at his backside the way the legs are positioned makes it look like his legs are caved in, you should try in look into it a bit and draw it to try and figure it out. It may be because its late and I'm tired but I'm having trouble wrapping my head around it...
Besides that, it looks good! As someone who doesn't have enough patience to color something, you did a good job!
