Part two.
Picking up where I left off:
Your kick is a bit too loud, that might be a bit of distortion I'm hearing in the section starting at 1:04 (and others like it). And because of the sidechain, your hihats are really, really hard to hear. :\ Clap is fine, though perhaps a bit too quiet.
Just a thought: What would be REALLY neat is if you recorded yourself playing the piano, live, to MIDI notes, and then used it in your song. ;)
The review's about done, so let me mention a few things I forgot to correct in the previous part:
"Next - your bass synth!" - I forgot in this paragraph to mention that your bass sounds seriously overpowered to me. Just lower its volume. :\
"If the review hasn't been helpful to this point (though HOPEFULLY it has XD) this is where it'll help for sure." - I added a LOT to the review before this point, so it probably has been helpful before there. :P
Well, that's about all I've got to say. I wouldn't call it your best by a long shot compared to some of your other songs (due to mixing, blatant samples, etc.) but it's getting there. :) It seems to me you definitely know what you're doing, and what you have in mind, you just need to refine your style and get a bit better at mixing. Hopefully this review (plus some) will help with that. ;D
