I like the fast piano-ish melody near the end
Welcome on NG, the beginning is quite ugly because it's just a simple synth playing notes which seem random at the beginning. I'd start the song with something else. The fact that the melody is played as an after beat brings a nice effect when you put in the beat. The beat is nice, bass is a bit old school and really not my taste (esspecially because the bass plays afterbeat). What I would like more would be that the bass would just play long notes and would be sidechained with the kick. The song itself progresses to something which is quite nice though.
I kinda disagree with magnetic-memories. This is much better than most of the crap which is sent to NG but it's not like "Wow, very good".
Btw, the voting system on newgrounds is really random and strange, most of the time, the crap reaches the top-5 and best of all time. So if you want some great tracks you'd better check the forums, some contests have some really good submissions.
But, you've got something with potential, keep it up!
