well its a good start. i will be brutaly honest with you in hopes that it helps you.
bends are out of tune, to correct this, say you wanna do a half step bend, play the fret that is after the one your bending. memorize how it sounds, now bend your note to this pitch. i reccomend using a tuner so you know.
same with whole step bends only play the note that is 2 frets away, instead of 1.
timing is off. i reccomend using a metronome and slowing it down a lot till you can get it at that speed and increase it a tiny bit till you can do it at full speed. i even reccomend going beyond normal speed and playing it faster the the original. then the normal tempo will be even eisier.
backing doesn't sound liek the song, that can be fixed. i can send you a better backing if you like?
