The pic is very blurry. it looks like hes wandering around in pea soup. I'm sure it's well painted as you say, but you just can't see any of the detail with the picture the way it is. Thats why it is scoring so low. If you can get a better pic posted then PM me and I'll have another look at it.
Errr...
Why only 4.2? I mean, it's not blotchy, the muscles are picked up with 3 highlights in stripes, the pants are ultra smooth, the metal is stained with 4 inks and highlighted with chainmail.
What's the problem?
