The intro's bass line really needs either some better dynamics or to be rewritten to allow the bass line to build up more significantly (eg. playing bass notes on strong beats only and building up to every beat). It feels repetitive and lacking expression compared to the rest of the track, it immediately gives the impression it's been written on the computer.
I hope people don't get discouraged hearing the first 20 seconds because the rest of the track is actually expressive and pretty well written. Even the reprisal of the intro feels a lot more life-like because of the upper layers. With a good intro I think this track easily gets 4.5 stars minimum, but I'm going to have to penalize the song for it to 3.5 stars (if there was a 3.7 I'd probably select that). The intro is a really important part of every musical piece, it needs to properly set the tone for the whole song and grab the attention of the listener at the same time. It's really bad if it sets a bad impression immediately.
Don't be discouraged though, like I've mentioned, the rest of the song is well written and expressive. Looking forward to more of your work.
