To start off, that first impact was loud. So loud it was clipping. Also, it's super repetitive. It had a couple parts where it got changed up a bit, but it still has the same 4 bar melody playing throughout mostly the whole piece. Also, something just seemed off about parts this song. I can't quite place it, but I think it may be the chords. They seem so random that it just throws me off. You need to use a more solid chord progression, even if it is cliche, and work with it. It will help you have stronger melodies. As I said before, you need to start putting more work into your songs. Success as a mediocre producer doesn't last long, and people are going to get harsher if you don't start improving.
Also, this is just my thoughts, but I think you should refine your work a lot more before putting it on any stores.
Please contact me if you would like to use this in a project. We can discuss the details.
