Its hard to judge the size from the pics. I can't tell if it is short or if it is thick! I like the shape and how pronounced your head is!
As far as the shaving goes in that one pic... some guys are hairy and it just doesn't look right to shave. Trimmed short is fine. I think you would look better with a close trim rather than shaved. I don't mind shaved. I do it myself, but i am a guy with light body hair! But I like your other, unshaved shots better.
