The start section (from 0:00 to 1:01) is rather repetitive and needs more effects apart from a sweep coming out of a LP filter. Also, the kick drum is drowning out the frequencies because it is so loud. Try compressing it, so that there is less low or EQing it for the same effect.
At 1:09, is that the standard snare that comes with FL Studio? If so, try and use something else because EVERYONE uses it, and it sounds like something from the 80's, which I'm sure is not what your going for.
At 1:16, add more reverb on that Crash and damp the reverb. also add a kick and add heaps of reverb on and compress it for those big, boomy, House drops. Also the lead from 1:16 needs more mid and about 5% more low band on the compresser.
At 1:46-2:47, nothing happens, I suggest you get rid of it and just replace it with 2:47 onwards, that'd be good (and then add the main lead into a LP filter from 2:47 onwards).
Altogether, REALLY good track for your age, try experimenting with other genres as well, and see if you can incorporate other elements into your track. It will also widen your sense of 'musical understanding'
