cool
lol, i remember back in the day when i was at your stage. im gonna say what people told me. now, it wont hit you right away but you have to keep expirementing and soon you'll be good.
ok, here we go
1) im gonna be honest with you. don't use standard FL sounds, like the kick it starts you out with. I would recomend the dance kicks. soemtimes just a kick and hihat will set a nice beat. also, dont use the low quality regular sounds in the Packs. try using sytrus, or downloading soundfonts on the internet (search 'soundfonts', that should come up wih alot of results). even effects you should change up. a good way to do this is to click on the button for each song in the Step Sequencer (F6). Then it will give you alot of options, like Pogo and reverse.
2) more diversity. unless you get a really catchy melody, you should definetly have more variation in your music. Try switching up the melody, using diffrent instruments, and adding in diffrent harmonies. great sounds to use in the backround are pads, strings, and synths, but make sure they are quiet and on-key. no cheap FL ones either, i recomend trying the ones in Sytrus-->Synth String. those ones are good.
That's all i have to say for now. Make sure you read that whole thing =P PM me if you want more help, and be sure to check my page out too!
Good luck in the future,
