ShadowBeatZ saidWell… I think it worth to add a bass line, cut a little somewhere in around 100 Hz from the snare, to diversify the drums line and do something with density of a track (+ mix can be made louder). Good luck!
So if you guys could just listen to it and give me some advice please?
Your mix lacks clarity, it sounds too compact.
Simple fixes like playing with the pan and the EQ might be just what you need. For instance, and like James told you, the snare does not fit into the mix.
I would cut in the low frequencies as well, boost the mid-frequencies and probably add a subtle reverb.
For your main synth, I would play with the stereo image when it starts going fancy at around 0:30, and so on…
You can probably find good tuts on the ABCs of mixing over at Audiotuts+. Good luck.
I’ve had some stuff rejected and I think most of the time it’s just due to the production/mixing/ect. They really only like to approve stuff on this site that sounds well mixed. I think your stuff sounds cool though.
