Can you elaborate on what you mean by "Space banner from Sonic and Knuckles"? I've played through the game a bunch of times. Do you mean the background to Doomsday Zone or something? If so the background is very bland, if it doesn't look any good would you like to substitute it for something I can edit which will blend much better with the Kirlia?
So you kinda want a Super-Sonic-Kirlia huh? If I can find a good pose online I can edit that. I would draw it myself but I don't have my tablet.
