This is an ogre I have been working on. Anything I should add?
Very nice! It would look much better with brighter lighting. 
Keep it up!
Fun expression, do you intend to give him teeth?
Actually a funny coincidence that you post this here now, I just finished my orc bust (=ogre same same)
Feel free to use designs from it in your sculpt if you want
I am not sure if I will give him teeth, because I don’t see where they will fit in. It would look to aggressive if i spread them out throughout his mouth, and it would just look strange if I put them along the edge of his mouth. I am considering a tongue, though.
