Not bad, it is off to a good start.
The music is from Sonic 3 (and Knuckles) end zone boss battle. One of the most epic midi of choice to remix in my opinion. You seem to be heading in the right direction. Who the composer is exactly you may need to research, because there was more than one composer for that game.
but it needs to be longer, seems like it cuts off right at the end...other then that 5/5 and 10/10.
As I Was Listening I Felt Like I Should Be Playing A Video Game. A Little Too Short Though. Wanted It To Be Longer. But I Liked It.
Please contact me if you would like to use this in a project. We can discuss the details.
