Not to shaby, has a nice glow to it with the off canvas light source. problem is I think you should of keep some better outline with back arm instead of trying to fade it into the fog/what ever it is. Also if that is a flame torch or spot welder, their would be a tad bright glow that would cast some light on the left hand.

There could be some shadow work on the ground,but I understand it was a speed paint. keep up the good work.
