I don't like the model that much (the waist is to thin, looks like a lady), but the texture is kickass. By the way you have a little UV stretching on the leg.
i pushed the waist out a bit, you can see it in the last picture of the flesh ripper.(sort of) Ill get a render of the old one with the new waist soon.
It's the texture I'm having trouble with, looks like a lot of random muscle. Though IMO the model looks pretty nice now that the waist is fixed, especially the armoured one looks good.
