This is kind of a double submition. First, I've simply done a repaint as well as a few minor adjustments to the Spider-man 3 "Venom" figure. I decided after watching Spider-man 3 again the other day to make him a bit more movie-accurate. I dremeled down his tongue as, for some reason, you never really see it extended in the movie. I also painted the inside of his mouth as well as a few spaces in between the jaw tendons a deeper red. I then painted his teeth black and overcoated with a white (with slight yellow tint) dry brush paint. Of course, the spider on his chest and his eyes needed to be more white than the strange colors they were previously, and his fingernails ('er...claws) needed to be a light yellow. One other minor adjustment was that I shaped his feet to look more like feet (as they appeared in the film) rather than a nice pair of dress shoes.
As I said, this is kind of a double, but the second wasn't much. I used the head of the Cap. from the Captain America/Nick Fury Legends pack, painted the hair a brownish-red, and popped it right on the New Goblin. I thought it worked well enough for a Harry Osborn look-alike head.
