FL presets!
The samples don't sound all that nice together. Choir sounds annoying how it's always cutting off. The effects and drums really have to go, it's all very cheesy sounding. Atleast try the sytrus presets or something a little more danceable. It might be ok if you use some more original sounds, maybe some good synth VSTs. Start exploring new sounds in FL, edit them, mix around the effects a bit, but please don't use the samples, they really don't do justice to the budding musician. When I was starting out with FL, that's kinda what I did, but once you look around, read a few tuts, you'll know how to get some real fresh sounds out of your music. I'm not saying I'm pro at FL, that's certainly not the case, just that there is a lot to learn about FL.
Good luck refining your sound. And don't take this review too harsh, experiment and practice is the key to improvement, and eventually, success!
