Questionable use of pitchbend...

This song lacks vision/structure. A lot of it doesn't make any musical sense to my ears. The beginning up to 0:46 could be kind of interesting, but ultimately sounds like you were messing with your pitchbend, landed on a few sour notes, then threw some drums on top of it... But here's the good news... 0:46 - 1:11 definitely needs to be expanded on, because IT SOUNDS SWEET! I would delete everything after 1:11 (except 1:40 until the end, if you like that part), and just expand the riff from 0:46. You can keep looping it and use it as a bassline, to add some chord progressions or leads/solos over it... I think if you experiment and invest some more time into this song, you could end up with something awesome! Good luck and keep learning/developing your sound!
