First off, the crowd effect is your enemy. I'd drop it completely, at least for now. Second, the synth you're using for a bass doesn't change. At 2:01 when some variation comes in, the bass just goes up an octave. Switch it up a bit, you know? Also, the bass synth needs more bass and less treble (at least on these speakers). The buzzing took away from the rest of the song. Third, I like the way it drops out at 1:18 (except for the crowd sound), but when it resumes it's the same basic thing as when it left. It'd be awesome if it drops out and then some crazy new section kicks in where the bass is dynamic with the drums working around it. When I listened to the midi file, I was surprised that you only utilized part of the source tune. You could work in a lot more of the source's chord progressions and it'd be better for it.
Don't get so caught up in the theme or the genre that you abandon creativity; take some liberties and this thing could shine.
...And don't take shots at your own stuff. It's irritating and has "defense mechanism" written all over it.
