I agree with Squeee, Inhe and Mystique too: maybe you haven't been properly practising in over six months, but you can still play guitar, and play it in this awesome way... you've been so good, I wouldn't know how to say it!
And sure you need practice but hey, don't forget that you've got talent by nature too, like with your ability with tabs, so... don't be too severe with yourself, Mitch.
Anyway, again, this song you played is one of the most beautiful, to me... good choice as well.
And the guitars you already have are beauties, you know it too, but I hope you'll get your Jackson soon anyway... I have a thing for that guitar too, it's my fav, I even prefere it to my also beloved Fender Stratocaster.
