He's holding the sword? Well, I think it looks like the sword floats because his hand then has a dark outline, while the rest of his body has a light outline. If you give all the weapons a lighter outline, it would look better.
The shadows are just... Circular. Oval. Whatever. It doesn't make sense that the bottom claw of the wolf and the tip of the soldier's shoe don't cast a shadow, as if they're just standing on a dark dot. Also, the wolf has a shadow to his left? Where does that shadow come from when the light comes from the left?
