its vERY good.. BUT might i add: i think the drawing would be a lot better if you give it some EXTREME darks.. like BLACK.. you do a good job with the lights and middle greys, but to be BOLD and complete, it needs the crazy darks.. so u could add that in some places.. word
I dunno, I like the background as is. it pushes it back when it's kind of underdeveloped, and makes the face stand out more. unbelievable amount of detail there, I can only imagine how long that would take. just awesome, that's all I can say.
