short loops are fine and good actually imo! my first tip, to paraphrase another's advice from a while back, is that if you say something is bad, then the listener is going to assume it *is* bad before they've had a chance to hear it.

as for this cover, i appreciate what you're doing with the 2A03 waves and the noise channel, but given this is the fami+ format, i'd consider using those expansion chips and some DPCM to get more out of the timbres and percussion available through those. for transcription itself, that's one of those realms where the practical "aural skills" side of music theory comes in clutch. training to recognize intervals is huge, and there are lots of websites out there for interval training and chord quality identification drills.

in conclusion, i like what you got and would love to hear more!

thank u! really appreciate the kind words. will keep this in mind in the future
