I'm probably the oddball here, but I absolutely hate how Super Sonic looks here. I don't know what it is about him, but his quills look absolutely awful in my opinion, they're way too thin in comparison to every other normal Sonic variant we've had, including this one, it's as if his quills slimmed out. If this is what the new Super Sonic is going to look like from here on, I will probably avoid using Super Sonic in SRB2 ever again.
Aside from that, I love how base Sonic looks, it really fits with how Knuckles looks now. (I'm one of the people who was opposed to the idea, due to how different Knuckles looked in comparison to both Sonic and Tails.) I've been following this for some time and I enjoy this aside from Super Sonic. Nice work.
