Feels like you shouldn't ask me to check out your other stuff unless it actually improves.. Same thing on all your stuff mate, the kicks are lacking.
Either you finish an entire track and get correct feedback that way, or you improve what you need to work on.
The melodies are decent though, but the point of using Nexus seems kind of low, would be way cooled if you had your own synths. For that matter, way cooler if you did all the work yourself ;)
