I really don't like the drum loop. The guitar is fairly lo-fi but real sounding and those horrible artificial drums clash annoyingly. Of course recording real drums is a lot of hassle (especially if you don't have a drum kit) but atleast try and find some better samples. Or make them quiter, or sit further back in the mix.
I liked the guitar and the chord progression. It has a nice driving force to it and whilst it's short it gets me into it's mood. I feel like this is a part of something bigger as opposed to a finished piece though. Do you have any ideas as to what you might add after or before?
