Nice work. Haven't seen you paint a guy in a while. Although the part where the bottom of the neck meets the top of the chest looks unnatural (looks hollow and "pushed away" to me) But other than that its awesomeness.
Very nice piece! You're great at drawing anatomy. The colouring looks fantastic. I really like how you've added the white mist coming up from the bottom. It adds a sense of subtle movement to the overall image.
