I. Character creation
Pick Nord as a race, first preset. I like the average build for him, as it makes him more comparable to the guy in the live action trailer. Leave everything else, including his hair and beard, except change his hair color to brown.
II. Apparel/Weaponry
You can make his armor and weapon set with relative ease early on. You need to make:
Iron Helmet
Iron Gauntlets
Studded Leather Armor
Hide Boots
For Weapons:
Banded Iron Shield
Steel Sword
Steel Dagger
I also like using a bow, but he's never seen using one.
III. Roleplaying
Try to get Fus Ro Dah as soon as possible, I prefer the horse named Frost to be his trusty steedm I also think Aela is a fitting spouse. He also seems to be one who'd join the companions. Other than that, do what you will.
