I don't know the character you're modeling, but I think the better thing you can do is to show his personality through his appearence. Seeing his body, I imagine he is a tough soldier, crazy for killing everybody who cross his way. So, I suggest you do with eyes what's more representative for the char personality. Instead of make snake eyes, you could search some references of tough people, like Charles Bronson, or killers, like Hannibal Lecter and use as reference for your char. Of course this is only my oppinion, and like THX has said before, it's your model, and you know what's best for him. But it seems a good idea to me.
The head of your model look a little square to me. I had the same problem with mine in the beggining. It's a good idea fix that now, and avoid problems in future!
