Since I couldn't begin to find the original "vamp" version of Damon, I decided to get another 1864 version and vampirize him on my own. I washed his hair and trimmed it a little, put him in modern clothing and he's close enough for me.

I actually kind of like how his hair lies on his forehead better than the original version I think. It might be a little longer in the back, but I like that too. I can still trim it up a bit if I decide to.
