Update 1: Mixed it slightly differently, re-recorded a couple of guitar bits.

Update 2: Modified the organ sound+reverb, reduced lead guitar volume slightly.

Any suggestions on the mixing/eq/quality etc would be greatly appreciated! Thanks to those who've already made suggestions and helped me improve it.

As I was writing it I ended up using various time signatures. It begins in 4/4, the first time signature change is at about 1 minute, for one bar of 21/16 before returning to 4/4. The piano section is in 6/8, which is immediately followed by 7/8 (when the guitars come in) and it returns 4/4! :)
