Well, its obvious that the track isn't finished yet . Do you plan to add some bass?
You need some FX to spice things up. Also some synths, ot pad or whatever in the hi mids and hi freq.
The main synth theme - give it a rest at some point, its a bit annoying to listen to it for 4 minutes non stop.
I dont know if this was helpful, but work on it and post it again.
