Awesome background and work on the armor.
Anyway, ...
He is in a swamp? For a minute it looked like it was frozen, but the shimmering in the front says otherwise. Is it a defrosting swamp? I'm just getting confusing messages about that part, partly due the colors partly due some details. Not sure something needs to be done about that. Just letting my thoughts flow.
The position of the wounded leg seems awkward to me (maybe I'm reading wrong the position of knee on the left leg), as well as the two left-most fingers (to the viewer) on his right hand. It seems like the whole bottom-left part of the works needs to be re-thought.
