@scoobyman : thank you for your comments
I try to work on the quality of my sound but there's a long way until sounding pro.
@moofi : yeah you're right may be I am a bit recycling some of my ideas but the fact is that I worked a lot on this track because it was supposed to be a song (with vocal I mean). And then when it failed I was like "there must be a way to release this track anyway". So here it is, that's not my most original one but I like it enough to publish it on soundcloud. Right now I work on my next track and it should should fresher (I hope so). Thank you for listening and commenting !
