I also think the shaker could probably come down a little bit, or edit the velocity some. It's interesting the play with the sfx in both ears.
I really think the chord progression could use more than just octaves up to 1:00. Like 1:50. That's not bad. Maybe study some music theory, lead writing, etc. There are some channels that I stand by, Signals Music Studio, Holistic Songwriting, Ben Levin, in order of least difficult to most complicated.
By 4:00 I feel like we should be reaching our outro, fade out, or something. We've heard the same bassline and chord progression. I don't feel like there's a need to drag it out an entire minute past that point. By 4:52 it's just octaves. That said, the stopping point at 5:06 on your one chord... or... note, would have been the decision I made, wherever I stopped it, given the progression repeats so many times.
I just wasn't able to get into this song. The progression is very simple which is not necessarily a bad thing. Nothing sounds glaringly bad. You've even taken some pretty good steps with your percussion toward being innovative -- although those breaking noises I would take down by about .5 dB because they're louder than your snare at points. I really just feel that everything settles on the tonic of each chord, and that makes for a listen that isn't bad, so much as it's kinda meh. Absolutely no offense intended. If you listen to my old catalog, I've really been there. I've been through it.
No matter what, keep making music. The more you do, the better you get. The better your workflow will become. Take whatever composition you think is aesthetically your best, has all your favorite synths to use and samples -- delete all the midi notes and just keep one of every sample you want to use in a muted track. Save that track as a template. Then pick a song structure you like, and make markers on that template accordingly. Save it again. Work from this template as you go, adding and subtracting as necessary. It will help save you a lot of pain with guesswork and keep your focus where it matters, improving gradually until the day you can look back and be proud of how far you've come :)
Thanks for coming out to NGUAC!
