Catchy
This is pretty good for a first song.
But there is always room for improving. I would first make the volume of the drum beat a little bit louder. It's an awesome beat but I can barely hear it.
Same with other parts of the song, the volume is low. I don't know if you accidentally hit the master volume button or pulled them down individually. You should also try to get some VST plugins with better sounds then what FL Studio just comes with, if you haven't already.
Overall, it's pretty good. Keep practicing, and don't listen to the blammers and haters.
As for tutorials, there are SOME good ones on YouTube, but most of them aren't really that great with explaining things.
