Oooh man whatever distortion effect you put on the guitar at the beginning got my nostalgia going so haaaard Just an icing sort of thing, but maybe if you put a phaser or flanger on it, you could capture the sound of the original track even more, but you don't have to.
Other than that, I'm going to jump on the bandwagon of saying that the drums are not mixed the best. Is the kick drum playing the exact same rhythms as the bass guitar, or even at all? Cuz either the bass frequencies on the kick are being cut out by the bass guitar, or the attack on the bass guitar is too clicky.
