How long have you been composing? Because I remember having the shittiest sense of music when I first started making/playing music, but as I continued I gradually got better at distinguishing different notes. Keep uploading! This does sound a little nooby (3osc arpeggio~ instrument from FL I'm assuming), but it's not terrible. You may have potential, but it's hard to say from this one song alone. Happy song writin'!
I'm trying to compose since 2008 but I'm not a tutorial guide guy, so I am figuring everything out chance ;) and I upload hundreds of low quality stuff because of that :)
