You did a pretty good job with the lighting and coloring on this! There are a few things I would like to point out though
The first thing I noticed was his earmuff and how its sticking out at an awkward angle (the one to our left). There are a few other places in the picture where the perspective is a little uncertain as well.
The second thing would be the reflection. What is he sitting on? This is something you have to decide when you make a reflection thats really important because it dictates how much detail does into the reflection itself. Right now it looks like he is sitting something like a mirror, is that what he is sitting on? If he is sitting on ice then you would want to make the reflection very blurry and soft. Another thing with reflections is that the angle is important. The reflection is always going to be bounced to you at the same angle it hit the surface at. In this picture the angle looks as if you are looking at it from much higher up. If it was actually a mirror you might only see up to his shoulders at most.
Those were the first things that I saw when I looked at it, the perspective and reflection.
nice work on giving things some texture so that everything isnt flat, clothing sticking to bodies usually looks really unnatural (you dont have this too much). try adding some more dramatic wrinkles, something that breaks up the normal contours. If you look at your clothes do the wrinkles fall straight down or do they stick off of you and change your silhouette.
Keep up the good work-
