You've come a long way man, nice tune!
For feedback, well I'd make some more variance for those sweeps, and try to add several sweeps at once with different lenghts (but balance them out) because right now they are too easily distinguishable, sound a tad flat and some end too suddenly. Just try to make them more natural and have more going on. Also, maybe tone down that little vocal (I guess it's from break?) a bit and I'd also try to make the bass even a little fatter. Good luck mate.
