Hey there @shubhra09
Hereās my point of view on this, I really donāt think that a Remix Competition is the perfect frame for learning & improving. Itās more something you feel ready or not to jump in and first of all itās a good opportunity to challenge yourself. Thatās might be the only the benefit linked to improvement, itās never a waste of time though.
Now letās face it, providing feedback on each individual entry & remix is simply not possible just because of the amount of time that this will required and most of the time itās a paying service on itās own that you can get from many production studios & some labels, because it takes time when done right.
Each remix competition has got itās own page here on the forums, itās a dedicated place for you guys to exchange about otherās tracks and to give feedback on improvement. Of course, itās not really happening because itās a competition with a potential release to win, so people are not very keen to provide feedback to others in this case, which is something understandable, but again it would be nice to see this more often.
Outside the Remix Competition frame, thereās also a āTrack Feedbackā dedicated topic here on the forums ( of course you canāt post link to Remix Competition there, itās forbidden to upload your remix to any medias ) but for other original work & tracks, thatās a place where you can ask feedback.
S.A team as also started a weekly Live Stream on their YouTube channel, and you are welcome to send them links to original track and if the track is picked up by S.A, they will provide you feedback during the Live Stream.
More on this here : Live Stream Announcement!
For any Remix Competition, here on S.A or anywhere else, itās a bit like sending a track to a label, in many cases just donāt expect to get feedback or even a reply, unfortunately thatās the real world when it comes to submitting tracks, better getting used to it IMO.
