ok, this is fr*** amazing, looks like dark souls and this: http://vignette3.wikia.nocookie.net/dragonage/images/d/d6/Tales_tarot.png/revision/latest/scale-to-width-down/292?cb=20150127094825
but more detailed.
I like the spadone. The proportions seem to be good. The hilt is long enough for such a large blade. However, the knight doesn't look like he's in a good position for a fight. His foot spacing is all right but his knees should be pointed outward instead of inward. It would also be better if he held a proper guard. With only minor alterations, you could make the sword blade go over his left shoulder instead of to the side, that way he's ready to strike his opponent or ward attacks.
Your painting style reminds me of Charles Monet a bit! Really good work. One critique, like patiger said below, would be to make the limbs more organic and directionless.
Cool stuff, though I'd say the hilt is too long unless the knight is actually very tiny and it's really a fancy letter opener.
Seconding the awkward trees and wolf butt. These are minor issues for me because the drama of the piece overpowers.
