Melody gets annoying
Sorry about the harsh score, but I really didn't like this piece. Some problems:
1. The mixing of the piano, I'd suggest to tweak the VST if you were using one, and assuming you're using FL Studio I'd say you'd use the "Dance Piano" preset and add reverb to the piano. Just a suggestion.
2. The melody got REALLY annoying, and it didn't help that it repeated through the WHOLE song. More variation would be nice. No, mapping the same melody to different instruments and adding a synth accompaniment that then evolves to an equally annoying melody doesn't count.
3. Slowdown part at around 2:40 sounded wrong, like the bare low keys sounded off, I'd assume you'd need to move some notes here and there. Also it could've been nice to let the main piano melody interact with that more heavily, like alternating between chords and the melody, and assuming you're using FL Studio I'd advise you to look at the sample project in "cool stuff" called "Hanging On (Remix)" the piano style there would really fit this song, if you took the time to rework it, that is. I also don't like how it immediately segued into the main melody again, a sweep sound effect would be nice. Or a crash.
Anyway all in all I didn't like this song, and if you're using something other than FL Studio try to apply my advice to whatever sequencer you're using. hope this helps, sorry if you got offended but hey, at least my review didn't go like: HAHA LOL DAT WAZ AWESOME
