Pinky : Love the guitar layering that starts about midway. The beginning plods. I'm not familiar with the original (I'm a post-Syd/Gilmour era Floyd fan). I'm also a King Crimson fan, but don't like itCotCK. Same for early Gabriel Genesis. Early albums from prog/space rock bands don't appeal to me for some reason. Anyway...
You added a lot of reverse effects and used stereo pan that gives it an old school feel, obviously intentional. I found the fast panning a little distracting but not terribly so.
The snare gets buried at times. Really the whole drums sit a little too far back for my mixing tastes. In particular the snare during the guitar layering sections and the kick throughout just aren't loud enough.
Otherwise nice mix.
