Explaination: Amy convinced Surge to let her do her hair, (the difference is the ponytail is more flared out :]) and that inspired surge to let Amy dress her up in things she wouldn't have thought to wear before :]
Anyway here's the rest!
The last one is a repost but shhhh don't tell anybody
So I have this idea of like a second Murder of Sonic The Hedgehog that's been brewing around in my head. Essentially, it's a costume party in a like big mansion and everyone is given an invitation by an anonymous person. Sonic actually dies, becomes a ghost, and has to get back to his body before he's trapped to haunt the mansion for all eternity.
Silver is a disco man/dancer, Shadow's a magician, Rouge is an Illusionist, and Sonic is stewardess. I still haven't figured out who everyone else is yet.
