Hmm
To keep this from being too repetative here are a few things you can do:
1. When the FX is filtered a few second in you could easily slide in a DnB style beat.
2. Same as #1 but you could use a gabber beat instead.
3. At the time(s) where the beat is completely gone, you could make the FX sound a little glitchy.
4. At times you could slow down the beat to add a dramatic type of style.
5. You could easily add an overlaying beat to the track for more variation.
6. Vocals could possibly help to enhance the listeners pleasure.
Ok, to let you know these are just my opinions of how you could make the track better. The track is still good and will grow on you. But it could be a whole lot better than it is.
