Finally got this one finished! So many things kept intercepting my work schedule and this one just dragged on >.<

Photoshop CS5 + 20 hours or so.
Airbrush + Texture brushes.
Dodge/Burn and Sharpen/Blur for finishing touches!
Same deal with the leather jacket as last time; 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. I really love adding in bits of texture like that!
