Thanks, and I'm still figuring out how to fix the repetition. 
Psytrance is almost literally trance on drugs. Psytrance is short for psychedelic trance. A couple of key things are the kick and drum, the synth special effects (like the "squelch"), and the emotional journey it takes you. I know thats like trying to explain "love" as "chemicals in the brain", but I'm new the the genre and there may be people who can explain it better than I.
Another key thing to mention is that psytrance got it's roots in Goa, India. That's how the very similar Goa Trance genre got it's name. Goa Trance is a more mellow form of psychedelic trance with more of a traditional Indian sound, whereas psytrance is more about experimenting with synths and is generally an insane form of a sound. 
I must also say that psytrance is a bit of an aquired taste. Like I said, I'm not explaining it well, but that's the gist of it.

They may be hard, but that's what practice is for.
Arrangement wise, I don't know the original, so I'll comment based on your arrangement alone. I know there are times when freestyle playing creates better emotional music, but pianists can spare a foot to keep tempo. Organists, not so much. My advise would be to get a silent metronome app or something to help you keep tempo. I also suggest either get a stereo mic or mix your mono so that it comes through both speakers. Audacity might be for you. Other than that, I love the arrangement. Very soothing.
