7/7/16 Update : Updated thanks to the Smash 3 Team

Hey, you all! It's been a while since I did something. Anyway, I thought the Smash 3C Retro Pit needed a bit more color in its life, so I gave more recolors to these already well done costumes. I hope you enjoy. I even gave some alternate wing choices for the Red and Green costumes and Even included a Pink costume!
