Poor quality and lack of good lighting realy hamper this photo. Its very hard so see any detail. I think that if you used a different angle of the face would help also.
with such an interesting subject it's a shame that the shot is so dark and it's simply a headshot. why not recreate the accident scene or at least light the shot adequately? perhaps have him tending to his wounds.
Oouch. Hope you or whoever this is is doing better! You neede more light in this photo. It would have helped to eliminate all the grain to the photo. Plus it is a little dark as well. Good luck and get well.
