Venomous snek heads without the vemon? It ain't natural feller! It's like a declawed cat! But I can understand the balancing issues that come with it. You could still make a sexual perk for the tf though. Oh, and along the lines of arms, you can do scale covered arms with claw tipped fingers. You could put hoods on the back of your hands for the cobra variant. Cobra Commander at his finest!
