So glad you finally got FL 20! you got really nice spacey vibe and awesome harmonies going on in this track, pretty nice to be your first time using FL Studio, the mix definitely could use some work, like in the drops, they are just a little but unclear, i don't know if this was your approach but i feel all the synths could have been a little bit more in the front, with less reverb (especially the chords), there is also an impact or a crash sfx in the beginning of the drops that is far too loud and high end heavy. Aside from that, the track might need some mastering, it's fairly quiet and dynamic from what i hear and see in the waveform provided by newgrounds.
