I would say that the backing track should be just a smidgen more prominent. I like the unconventionality of the opening riff, the middle of it is a bit weak but it ends strongly. The bending seems a little much at some parts, but it does work nicely.
Second riff is pretty good.
Third is good as well.
Fifth and on would be a good part to switch it up a bit make it a little more interesting, create some contrast towards the rest.

In general I say its pretty good.
