Nice But Could We Please Hear More? =)
Great start, but I have to agree with Xalder1 about this. It's very unfinished. One point I will make though, is that your description sounds like you don't like constructive criticism. We have to acknowledge criticism whenever we make something. It's a good way to revive our works, as long as it's in a good way. Don't get me wrong though, this is NOT a bad remix, it just needs a little tweaking.
To DoobyTimePiece, no Green Hill Zone was not in the second Sonic game. You have it confused with Emerald Hill Zone. If you thinking about the Master System/Game Gear version of Sonic 2, there IS a zone that sounds like it, but it's called Green HILLS Zone. However, Emerald Hill Zone in the Sonic 2 Beta version was called Green Hill Zone.
