By my looks, what kinda roles ought I play in movies?

I'd be more interested in the tone quality of your voice, than just your looks. Movies are more than pictures; an actor has to convincingly depict an actual person. Someone who looks good, but has a weak or high pitched voice wont get the part. I suggest, if acting is what you want to do, get voice training.

You know all that comedies where there are college boys hanging out together. They are always different: the party animal, the total nerd, etc. But there is always one guy that wants to make a career, to have a serious relationship and he is always hard to be turned on to do something crazy. I think you are the right choice for that guy, because as i can see you can be serious and funny.

P.S. I don't want to insult you, Peace Bro :)
