This is the first thing I have ever mixed (except for me and my guitar). I spent about 10 hours on it. Struggled with the snare (from the room mics) and I think there's a slight left-of-center bias in the overall mix.
Welcome to the fun Nice job for your first attempt at this many tracks. I might suggest a tad more compression and reverb/delay on the lead vocal. Regarding the drum room track, a bell boost at 5k should help a bit with the snare. I would rely a bit more on the close mics for the snare and kick, too. The bass could probably come down a small amount, too.
Firstly, many belated thanks for your feedback. I tried your suggestions and they were great - naturally
I became a hermit and worked on it an awful lot - I thought I'd try out for the mix competition just for the sake of doing so. I had learnt a tremendous amount largely due to the wealth of knowledge on this website.
Of course, I needed a goal in mind and it was to preserve the ambience of Abbey Road and Lyndsey's lovely tone. Being quite a bit older than I used to be I used reference tracks such as New Kid In Town (Eagles), Good Year For The Roses (Elvis Costello) and Blue Bayou (Linda Ronstadt). I used minimal compression and EQ mainly to get rid of clutter. I applied a tube simulator to the final mix which warmed everything up.
