what you're talking about is becoming autodidact. Music is - for some people - something you can learn to make yourself.
and you're getting there, i can hear that this song is pretty harmonic. the melodies you use are not too simple, especially the bassline is good. i like how you managed to have multiple feels to the track. the use of transitions is also pretty decent, except at 1.30 where you bring the other melody back out of nowhere... yeah no dont do that :P
also, electronic music isnt only about melodies and song structure. its also about how you work with sounds - which im sure you have been doing, but it could be alot better. just play with buttons some more, try some more effects.. you can develop a better sound along the way.
just giving you advice as far as it helps.
Not really autodidactic. That would indicate that I was learning music theory by myself instead of learning it from an instructor. I'm talking about NOT learning music theory, since it's very involved and can get incredibly complicated for even simple songs like this. For a music hobbyist, I think it's completely irrelevant. The most important thing by FAR is developing your ear, which doesn't necessarily have anything to do with theory.
I personally didn't think the transition at 1:30 seemed out of place, but that's just because I had listened to it over and over again. And that same transition repeats two other times in the song (i think).
Thanks for the advice! I'm always open for constructive criticism.
