Alright then, so where do I start?
He's Nordic, very blonde hair, pale blue eyes, fair skin, etc. The left half his head is shaved and the right half is worn long and braided with many (usually) silver beads of varying styles. He's got a pile of piercings in his left ear and a few in his right. The actual earrings he wears varies but they are usually hoops and he has extra large holes (about half an inch) in his earlobes, tribal style, with one dangling earring that hangs through the hole in his left earlobe. He paints a false tattoo on his left cheek as well, in black eyeliner.
Clothing wise he wears simple, dark t-shirts with a military surplus style bomber jacket (fur collar), cargo pants with chains hanging from the waist, and heavy black boots. If he's not wearing his jacket you can see his tribal style armlet tatoo on his upper left arm.
He's a street musician, and plays guitar.
Doesn't matter to me if you want to do just a full body, bust, or just a face, and I can dig up references or things for you if you need them. Here's a rough avatar I made of him. It's not perfect (his hair should be lose) but it's what I managed at the time. Ignore the skunk. That's supposed to be his pet ferret.
Rodent. Yes, that's his (nick)name.
