Two things that bugged me, the first is the drums, I didnt dig the compression all that much, would have been better if you sped up the release or compressed the cymbals separately from the rest of the kit. The other thing was the lack of spacialization. It kind of makes sence for there to be a lack of panning effects since VG music back then was mono, but it would have been nice to get some spread.
You got skills though man so keep going :D
