Nice job, but could use more variety in the piano
Funny, while I was listening to it I kept thinkin of this track I uploaded a long while ago (Under Control); it's got similar piano, but it's more hip hop than march. Anyways, I thought your track had a great sound, good selection of instruments, but it's also really repetitive on the piano riff (JUST LIKE MY OLD TRACK!). That arpeggio you have running the whole time gets old after about 2 minutes. My suggestion is to come up with a different way of padding the midsection of the track or maybe shortening it to about 2:30 - 3:00, if you feel like I do about it.
Still, I don't mean to be harsh here, it's well done, and it's well mastered. Nice Job. Also, it's not Hands-Up trance (which is starting to annoy me cuz there's just SO FREAKIN MUCH OF IT around here).
