Pretty good. A couple of the bends were a bit off I think. Also, it would sound a lot better with some distortion.
Well, it was a bit difficult to hear your guitar part over the backing track. Adjusting the volume levels of the guitar track and backing track would help quite a bit. Also,it seems to be missing that signature Pink Floyd sound. Some light distortion, and a bit of echo/reverb would help remedy that.

However, that said, your playing seemed spot on. Nice vibrato, accurate playing, and mostly great bends. Keep up the great playin!
