Execellent first go.
Holy Shite! Those drums! They totally gear me up for some serious... something! I also really dig the guitar layers that come in after the drum bit, I love layered instruments. It somewhat reminds me of Incubus.
The honest criticisms I have with this, are that each section of the song seems like it could build into something much bigger, especially with those drums. But at the same time, this is why I love first songs. Just that unbridled experimentation. Start working with some structure and I think you'll have some mind-blowing stuff coming down the road.
