I like the psychadelic rendering you have going with the markers. It really adds a graffiti and gritty quality. The proportions seem off because I would imagine Savage Dragon to be much bigger bodywise. The veins also seem a bit too much like vines. I would outline them and then merely suggest some of the time as they wrap around the musculature. Well those are nitpicks and you draw how you draw but thats my two cents. I like your work anyways, you know that.
