Must have missed this thread for some reason.
Really like the texture on his crown but a bit unsure about the double tusk on the upper mandible, as it looks a bit redundant to me. Doubt in my mind probably just down to it being unfamiliar. I also appear to be in the minority on this point so please ignore. However it's good to see someone trying something a little bit different without straying from the path too much. I must also applaud your sculpting skills as you're obviously no novice. Please keep us updated with progress.
