All my characters have been basically the same. 1H / Conjuration combos, usually either Breton, Dark Elf, or Nord, because I like starting off with some elemental resistance. I tried an Orc assassin once, but ...
I've tried to vary my play style, but it always seems to come back to 1H with shield, and a little conjuration. Destruction magic is essentially worthless, IMO, when you can do 3 - 4x the damage with a weapon. All my characters are heavy on archery, but only in sneak, as (at least on PS3) I have a game that only moves 1/2 to 1 second after I move the controller. Doesn't make for good combat shooting.
My 3 main skills are...
One-Handed, always, with perks up to decap.
Light Armor, always.
Smithing, at very least up to Elven and arcane blacksmith.
I push alchemy and enchanting as far as I can too.
