There are places on the internet where you can go get flamed even if your track is good, but this is probably where you’ll find the most constructive criticism or encouragement if you specifically ask for feedback.
If you have completed tracks then starting a topic under the “our music” section is a good start, you can request feedback or state the type of feedback that you’re looking for to make it easier for people to direct their analysis.
You can also just post music and if people enjoy it they usually hit the heart button, but that’s not necessarily going to inform you of areas for improvement. Unless you act inappropriately most people here are generally polite even in offering criticism, and like you, they’re also looking for a community within which they can improve themselves and their music.
If you’re looking to get ripped to shreds you might have to try another site, but for most people this is probably a good place to learn from others with more experience. I’ve certainly learned a lot from people on this forum and if you’re hitting a dead end with watching youtube videos, sometimes searching old posts or asking people with an actual pulse about the things that aren’t clicking can be very useful.
TLDR: asking for feedback on tracks in a topic you start for that purpose and update with works you want critiqued is definitely an acceptable use of the forum. Whether or not people participate is up to them, but there’s no guideline that says don’t do it.
You can also use existing threads which people already look at and ask for feedback there if that’s more your style:
this is mostly people posting completed tracks.
this is mostly people posting parts of jams or bits of synthesis, some full tracks pop up.
this is a thread for non-electronic genres, people still share all kinds of music in the other threads but this is dedicated to that.
