Pretty good mate, I feel like you maybe used a bit too much distortion on the tone. Brian May's tone is pretty hard to replicate though to be fair, especially with the whole reverse-phasing or whatever it is he does with his pickups! Having said that the playing was nice, bends all in tune.
At 15 seconds, that little run up he does it a bit more fluid than the way you played it.
All in all a good job though mate!
