Hey, I just realized that you added a preview for Melee Sonic. The recolors looks pretty cool, seems you got based from other characters of the franchise
I just have a small comment about Sonic's color (blue/default) being a bit too bright IMO. I guess maybe you went for a Sonic Heroes-ish tone, but don't you think that it would be better if you used a tone more like the one on Sonic Adventure DX/Sonic Adventure 2: Battle? You know like a darker blue.
Plus, those two games were exclusives for Gamecube, same era as Melee (I know Sonic Heroes was, too, but it was also on other consoles).
