What an excellent clutch of comments! And thanks very much for the rep, all!
Lots of food for thought on the next stage. Good stuff. I'll definitely be thinking about what you've all had to say when I get back to work on this. Might be a little while yet - my next post will probably be some finished interior stuff that I'm (mostly) doing in 3d - eek!
Thanks again guys, excellent community here.
