Okay… I think I know why you feel like its “crowded”…
In the first 0:43, and I think it goes through the entire track, the three elements aren’t aligned on the down beat…
The initial plucky metallic toybox melody has a lilting tempo, that competes a little with the synth bass. They should either mirror each other, or be a call and response back and forth. I would say adjust to follow the synth bass line exactly, since its so good and structured, and is the foundation of the lovely synthwave sound.
Also, there is a second plucky sound that is too frequent. Itsa nice accent sound, and should come in every other measure, also on a down beat, then you could transition into it replacing the toybox pluck as a variation on the lead, because when the beat comes in the second sound fits perfectly.
Finally, the beat doesnt always follow the structure of the synthbass… it doesnt have to all the time, but too often the beats arent aligned…
at 2:20, it sounds like two different synths lines are playing at the same time… but the two plucks are great together…
OKAY! Im done!
whoo boy, this feels really uncomfortable doing this… I hate criticizing other peoples work… but I really like your work, so its good that I can be involved in your process…
plus, its a way to REALLY listen to other peoples music… usually I just give a cursory listen to give a like here and there… but to actually really listen is something else…
plus its good for me to hear what you think… to see if I actually know what Im talking about or not. I am prone to hubris!
Thank you for letting me do this!
