it sounds like you're still learning how to use FL so i'll be gentle (sort of)
the different bass synths that play together are out of key, the crash sample doesn't really fit with the kick/snare basic samples. needs more interesting percussion elements and syncopation (i.e. percussion not just hitting on the beat)
oh, but i like the little lasery sound on the off-beat. maybe you could try to make some more minimal acid/electro style stuff?
