just another head.
CC are welcome to improve it.
Thanks
The modeling looks good … particularly the face. I’d like to see a profile render, because it looks as if you’ve fallen into a classic trap. Did you use a photo for your reference? If you did, the person being shot either had his head tilted down somewhat, or the camera was looking down on the subject. It’s the height of the ‘dome’ of his skull (too high) and the position and size of his ears (a touch too big and way too high). Try taking the mesh resolution way down and using the move tool to readjust things. See if you can get a book on anatomy, as a few skull reference photos really help to get head proportions right.
The other thing is the neck is so like a straight column that it’s distracting. But necks are fun to sculpt, so I don’t mind pointing that out. Good luck … this model has tons of promise. 
Moochie , thank you very much. I don’t use reference.
