Guitars, that mellotron thing, panning placements - all work! great loose feel throughout, loose in a good way. If this were my mix I'd be tempted to turn the lead vocal up and the guitar solo as well. The vocal performance is too good to bury it with a volume that is lower than the panned guitars. Just a thought - I'm not familiar with the original so maybe that's the original mix you were modelling?
It all brings a smile to one's face, doesn't it? Good job!
