The pieces are recognizable if you have a reference handy you can flip through and pick out what you want... I can't say exactly right now beyond the legs being from Mindbender and the arms are from a Crimson Twin.
Second Chance Project
These are my best. I want every figure that was decently conceived, but got screwed come time to make in plastic to get a second chance.
This is probably my favorite custom I did. I loved Sand Scorpions and the original figure was atrocious. If nothing else I liked the guy because he was one of few Cobra troops that was not labeled Viper... because that got tiresome fast.
The only figure I did that competes with this is my SCP Flak Viper.
