Hey

All the notes are pretty much right. The main sound you used throughout the whole song which followed the melody started to get repetitive. If you widen your selection of sounds it would improve your songs by heaps, personally I think the FL defaults are really plain. PM me and I might be able to get you a hold of some new sound packs and stuff.
Ruddy88 said it all, cant really think of much else to add.

good

as far as your piano rolls go its good, very standard instruments though, they all sound like 3osc defaults, i think thats analogous phattus and jr bass or intregue used through most of it, try using the sytrus plugin and trying to get some less homemade sounds. i liked the drums, the kick was ery distorted and punchy but i liked it like that, other than that id work on making the overall song a bit more involved, it seems too hollow if you get what i mean, put in some background ambient noise or a high pad or something... thats my opinion anyway, keep it up
