I was going to mention Jonah Hill. It's hard to find good styles when you're a guy with hair that's thick, frizzy, curly, really wavy...or generally anything not straight. Seth Rogan is another guy I look for with hair ideas because his is sort of similar to mine and he has a sort of similar face shape. Generally with a round face you want more hair on top than the sides. You could come in a little closer on the back and sides and be alright.
