The big long-haired nord dude with the claymore. Something out of braveheart :rock:
The breton mage woman
and then I generally either do a male dunmer assassin or female bosmer thief, or both if I have time.
I've done hybrid crap, one particularly interesting combo is an Orc with the atronach birthsign. Gives him a big magic pool and a high magicka resistance, but you get the orc benefits of high endurance and good blunt skill. I generally make him dark red too, because red orcs are the epitome of badass, none of that silly bright green skin for me. I generally pick a way I want to play, and build a character to suit that.
