I'm listening on a laptop, so very limited frequency range, but the mix seemed good here. I like the guitar part and your vocal is cool. Drums sound programmed to my ears, but that's sometimes a difficult instrument to make real sounding. What did you use for drums? When possible, I like to use MIDI loops that were played by real drummers. You get the feel of a real drummer, but the freedom to do what you want with the sounds and the ability to edit parts that aren't quite right.
I used Superior drummer 2.0, and my custom Avatar kit. I didn't use anything complex loop wise, I thought I would just keep it simple, perhaps too simple?
I don't think that it's too simple. Simple is good most of the time. I think it's that the kick and snare patterns never really change. Maybe a different pattern in intros, verses and chorus? It also seems like there is little velocity range. It's not horrible, it's just that within a very short time of listening, the thought popped into my head that the drums are a little stiff and sound programmed.
If it were me, I'd try lighter velocity in verses. And I'd probably work out a different pattern for the kick in different sections to help the listener differentiate whats what.
