Heya, first of all: Did you record this playing one instrument at a time, or did you record the whole thing in one go? Apart from a few minor mistakes, it's pretty faithfull to the original and it sounds pretty good as well. Too bad you didn't record the vocals as well, but that's only a minor issue. Perhaps you should've played the singing part with a synth instrument or something, to fill up the empty spaces in between.
And that guitar solo must've been a pain to play on the keyboard!
All in all, a job well done. 4/5 and 8/10. Keep up the good work ;)
