Ok!
I'm sorry if I'm harsh, I'm only trying to give advice. Keep that in mind :3
Correct me if I'm wrong:
DL_The Funk set as a re-stretched or sliced drumloop at 100bpm
FL Keys at default or concert piano.
I won't fuzz about the ambient background because I find it fitting :)
The problem I have with listening to your song, simply put, is tempo and choice.
"The tempo" for the score itself is great but the drums don't cope too well in my opinion. Even though it isn't exactly horrible, the beat, it sounds odd at that pace.
"Choice". This choice is by no means your fault I think but I urge you to search the internet for something called "CvPiano" or "Giga virtual instrument piano". It is a better "choice" than Fl keys, honest :) It prevents the attack, however the velocity, from being a dull constant for example. The best thing about CVpiano is that it is completely free and can be really good when properly tweaked.
The score in itself is quite easy and minimalistic which isn't a bad thing and I guess you get away with the double taps later on in the song.
I would've given you higher than a six if it weren't for the drums and choice of piano. I hope this helps :)
