After listening to this I felt like someone is still learning the way to compose something. Since this review-function is made for saying useful things, so I decided to be honest to you.
This song is supposed to be something depressing. It is, yes. This motif begins really good but after the beginning it doesn't develop anymore and it repeats and repeats and repeats. There is no musical soul in this piece of work. But you can do better!
My music teacher in school would say, that this is supposed to be in a movie or something. Without it, it doensn't have the right expression and gets boring. I'd recommend you to spend more time and let your fantasy out of your mind to develop more complex and better compositions! Just sit back, hum something and you'll get something useful very quick. If you haven't read anything about harmonics and stuff, I'd recommend you to do this, too.
It's not about the soundset I'm talking about but about the composition behind this, so don't get me wrong.
After you asked me to review on your song in your review on my song (Which was really positive, thx), I felt like helping you than saying something like "Wow this is awesome m8, keep up the good work". Don't be angry on me if you feel insulted because honesty if something very difficult to express.
I hope I could help you with my advice!
