listening through to the end, really nice separation and clarity generally.

I'd turn down some of the backing vocals in places (maybe even take some of them out, they sometimes seem a bit intrusive, need blending in more). but generally those are very good mixes, much better than anything I've ever managed in my own dabblings in home recording...

By the way, if you post the same request on this website here, you might get some more tech-y, geeky responses:
