So for the next monster in my series of monster busts, I decided to do a little extra to this one.
For this one, I used a two light set-up, and then threw in a lightning globe behind him. Since the exposure was set for 30 seconds, I slowly and carefully ran my finger along the side of the globe, creating the lightning aura you see. Then in Photoshop, I tweaked it a bit the levels and saturation a bit, and used a gradient to remove the trail my finger left.
