So far, I have only done Uni. I really wanted to make the hair spiky because she's now a cool, blue hedgehog from the '90s. I wanted the outfit to really feel like it's from the '90s so I gave her a tracksuit. Those were pretty big among rappers at the time and it's fitting since Sonic is super athletic. I'm gonna go eat lunch and figure out how I'm gonna turn Mettaton into Amy now. I still wanna go with something from the '90s so it matches Uniqua but, I also want to try including some details from Boom!Amy's design.
Edit: Mettaton has been added and he's in Modern!Amy's dress! He also had to get better lashes for this. Just be careful since he has a massive hammer. But it's not a real one. I also noticed Uniqua didn't have a tail so I gave her a spiky one because she's a hedgehog.
