The great thing about this piece is it how it plays on dyamics. The synth in the beginning literally pulls you with its sharp crescendos. Its great!
The flow of the song is amazing too. The only thing I can suggest is a little more melody on the top, i.e. a synth lead, strings, or a singer (wink wink!). I see a lot of potential with this one. Depending on how you want to expand it could easily be hip-hop/R&B-ish or the instumental by itself can be considered techno-ish.
Whatever you choose to do, I can honestly say I'm anxiously awaiting the final product. Great job!
P.S: If you want a singer, get at me!
