I too am not too fond of the leg. It does look a bit unatural. Maybe if both legs were showing. Not seeing the other leg makes you wonder whats going on. Why is he walking like that? When doing a full length image you really need to show the full length. Again using another photo analogy, you rarely see images cropped around the calf. It creates an uncomfortable tension. Its either full length to the ground or 3/4 view. In looking at it for while I would probably have cropped it just above the left wrist.

I like the snow idea and some trees off in the backgroud. Kanji's idea of the sky is perfect. A nice gradation from dark to light will give it a nice framing which will keep the eyes from wandering off the page.

Your doing a great job. Cant wait to see more.
