It's not bad...
I think my biggest problems were the melodies and the transitions. Melodies first. Like, the first 15 seconds is a melody that seems like it doesn't really go anywhere for me. It's hard to explain exactly how to write a good melody - it's one of those things you sort of learn subconsciously. But the initial one has all these jumps all over the place, and that usually doesn't work (unless you're doing arpeggios I guess...), you usually have stepwise movement (like C-D-E) with a few occasional jumps.
The other thing that you can think about is transitions between the different sections. Like, right now it's pretty hard to tell that all the different sections (that you mentioned in your reply to BlueOceans) exist, and that could be because there isn't much that differentiate the sections. It's as easy as changing the instruments, or adding in a crash when the new stuff comes in, but it is very important because otherwise your song feels directionless.
Other than that I liked it. I thought it had a nice chill aesthetic to it, and it was pretty enjoyable to play in the background while I did stuff. Keep it up!
