Harrison's has three main pic bases:

1. Chris Jericho. He is one of my favourite wrestlers, and when I first started roleplaying I based my character initially on him (this was back in 2007).
2. Christian Cage. As I made my character 'more original', I decided I wanted someone with short blonde hair and a short beard, who was about six foot and two hundred and twenty pounds - Cage fit the bill. I also liked the look of him and he fit my picture of Harrison to a tee.
3. Josh Holloway. Eventually I transitioned Harrison to the millionaire play boy living in Malibu, CA, I felt that Holloway's surfer play boy look on Lost was the perfect image for him. Holloway also looks bad ass enough to pull off an arrogant, egotistical side that is Harrison all over.

I have tried experimenting with Harrison's pic base, but of all of them I find Holloway to be the best fit.
