Yup. That helps alot. No offense, but you have ALOT of work to do if you want the Orc to look "correct." Wrist or no, their musculature is humaniod, so it's important to get it right. At the moment the biceps and forearms kinda blend together like a sock is streched over them. . .pecs, the abdominal area, legs. . you need to keep working to make them look right. . that said, if you plan on clothing him, don't bother.
On the other hand, the head looks pretty darn good. Keep up the good work, I'm looking forward to the finished version!
