Catchy melody, but a few problems
There were quite a few things that I think could be improved. The lead synth was rather dull, not to mention it needs a quicker attack, almost a little bit punchier. And the stock FPC samples really aren't doin it for me :P If all you have is stock samples... then try layering a few of them together to get a more unique sound.
Also, if you created this entirely from scratch, you have quite a bit of potential, but I would look up how to use an Equalizer, and the make effective use of the mixer in FL Studio.
