My suggestion is not to use so many "saw" like instruments. It sounds like they're all in the same spectrum which is one reason the song sound kind of flat. I feel that you have cut to much on the equaliser. Also the low end is not there, at least I can't hear it. The arrangement and song structure is good. You make changes in the song and things flow on in a natural way. That is good. Also I would suggest some reverb. Right now it sounds kind of dry
I really do think this is a cool idea! However i agree that there is need for some diversification in the use of instruments!
