Couple of mistakes here and there with timing but overall a fitting tribute to the legend.

The tone sounded a bit beefy i dunno , maybe less bass and more mids and treble with a bit less distortion.
Love this song - my favorite Gary Moore song. I know from personally experience that the bends on this song can be quiet difficult and also getting a good tone that fits with it is. They are the two things I think you need to work on (As do I when I play it as well!). Just follow what was said above for tone i'd say. Keep it up though, sounds great!
