About 30 hours in Photoshop CS5. A good amount of time was spent trying out different colors because the photo ref is in black and white only ( http://www.starsentertainment.com/images/stories/Sons-of-Anarchy-Tig.jpg ) so getting it looking as natural as I could was pretty challenging.
Lots of skin texture brushes and detail :)
I was dreading the leather jacket, but it was actually quite easy. I just painted in the tones as I normally would with the airbrush, then put a leather texture photo over the top and worked it in with a little Doge/Burn tool for the highlights and shadows. Couldn't be happier with the results!
