Well...
It's nice, know it.
I like pretty much his pants, but try to work a bit on his cape.
The hair is ok, maybe you should consider changing his eyes.

The muscles... he has a lot of muscles (maybe too much) but his back is very small. Make it like more fat.

The wolf version... add more hair to his tail and maybe hishead.
His head seems to be pulled back towards his back. Move it horizontally a bit.
I think it should be all for all...
change those small dettails and post it here again, ok? :)
