Pretty good!
Pretty good for an unmastered song, ill give some tips that might help you in your mastering of this track haha:
Well first, the piano...srsly dude dont, never again use the fl pianos k, those pianos really suck! I'll recommend you to either find a good piano sample or download a good VST with virtual piano on it like, Orchestral, Hypersonic or Nexus, but well if you dont have any money for that, you can still fix that piano, just try adding some FX like reverb or delay, that should work well.
Well second, at 00:36, turn up the volume of those drums, I know what your trying to do there, but trust me it will sound much better with those drums vol UP!
Then at 1:01 you dropped the bass! And the cool part comes, the only bad thing there is that your filtered lead is way to low, try turning the vol of that thing up! And finally your kick, just make it a lil bit harder cause in dance music, without a hard kick, your try just...doesnt work, so make that kick punchier haha!
Great remix, of a great song!
Keep it cool bro!
