hey whats up, the beepy melody is great, try to add something in the background like an atmosphere of a soundscape to make it more impactful, also the kicks, the kicks feel really weak, it doesnt feel like the melody is riding with the kick, almost feels like the drum is just an background noise beside the melody, this isnt that bad i've heard worse stuff on Newgrounds this aint bad :) keep it up and work on your drums and the way you build your song, let me know if you post a new song, id gladly hear how you've improved.

First of all, I admit I haven't real knowledge about composition, still, I'll do what I can (with my poor knowledge both about music AND english) to help you :P

Bass are very important when it comes to provide a solid base to your song. I say that because I think
your song could improve very much just by adding a simple bass to hold it, otherwise, it soubds like... it lacks something. In my opinion, those parts where you decrease one octave, it sounds weird, it MAY be better if you just keep the voices in that octave (0:51 to 0:54). Also, I feel like the drums (or whatever D:) need a little more variation.
Finally, please don't take any thing of what I've said bad, as I'm saying it only to help you (try). I hope
you understood most of what I said o.O
Have a good day. :D
