comic guy

hmmm...sleeping over problems does help. I'm full of ideas for my comic guy...his looks, personalities, attire et al.
I feel I've always done the thing I've wanted, and am generally happy with my looks, lengths and breadths but I also feel that things could have been better. maybe I can give my cg the dimensions and general feel that I've always wanted - 6 pack, long hair, a goaty, decently tall...
I had made a few sketches with this in mind, but after a few sketches my cg started looking like Aragorn from lotr. But I'm sufficiently satisfied with it. I wanted my cg to be a teenager, intelligent but detached...kind of a loner but with an attitude like Howard Roark. The problem with having such a sharp character is that it does not give me much room with the jokes and wise cracks. I'm being 'parochial' even before I could start. Which brings me to this question...do comic guys always have to be comics? I think this is a no brainer. No one would like a comic character who is snobbish, talks more through his eyes than mouth, and is aloof most of the time. But this again brings me to another question - Calvin is sometimes very amusing without being slapshod?
this is going to be a long journey...
