Honestly...I don't like it all that much as of now. Maybe a different sound for the melody. It gets old really fast. And I don't know if you changed any part of the melody for this third version, but it still sounds like a pure midi rip/cover. I do like that pad synth type thing in the background, it's pretty nice. And the drums are okay, maybe some more variation. I can't take five minutes of this. *pauses song*
In the words of hewhoisiam,
Just work with it. I'm still a n00b, but I can tell when something's not gonna make it.
I know this all sounds harsh, but don't take it personally. I'm just trying to help.
