Definitely needs some moar work. As you mentioned, those samples need some adjusting. But I really like what you did with this!
Mastering is a bit shaky in some areas, so that needs to be tightened up. It's a little much in the high end. Mess with the pitch a bit on those higher synths. :\
And most importantly, YOU HAZ NEED MOOOAAAARRRRR BASS.
I can dig it.
this audio is awesome. it's slow paced and sweet, and it sounds retro while still hears fresh.
Please contact me if you would like to use this in a project. We can discuss the details.
