The first is good, but a bit too repetitive. Most of the top drum and bass artists 'evolve' their sound throughout the track, with the beats getting more complex or whatnot.
The second is a bit odd. The slowed-down break has been quantised so much it sounds really low quality, and doesn't really fit with the rest of the instruments. I like the clean passage with the xylophone-esque synth though.
The third is the best of the lot. The eastern-sounding melody works well. However, Try taking the reverb off those drums and compress them, it'll give a tighter, punchier sound that I think will still fit.
Overall I like them all and you can hear clear progression, which is good. シ
