well tbh
You will prob need some EQing and Compression on your kick...
and there's not guite a line in this song...
you just change some synth sounds to keep it interesting right?
well, thats not a way to make a song xD
Besides that, your piano is just genius....
i dont know how to review this since it hasnt any form of build-up or structure xD
and im sorry for my bad english tho, im dutch, just like you xD
oh and if you need ANY help, just say so kay?
Cheers
