My problems with the picture is:
1.The guy is holding the sword by the tip of the handle.
2. The guys buttom half look messed up for example, one legs look to long from the kneecap down, while the other looks like he has a sprained ankle.

But other than that it looks okay.

Overall,this is great but there's a few things i personally consider bad:
-His sword-grip looks really weird
-His right foot's pose make it look somehow broken
-The wolf doesen't stand out too much :p
