Max: don't worry. I'm not mortally offended by your comments. I try not to use 'em, but smilies make everything bad go away.

Chashio: those notes aren't meant to be legible. Not yet, anyway. They were just done for my own reference. Thanks for the comments, though.

To be honest, I don't really like the way sketchup looks with this; it's a bit too digital (and I'm not very good at it). My plan was, after modelling the city, to trace over it and redraw it from, that's right, a birdseye view. That way I can make sure all the perspective and proportions are accurate, while the whole thing has a hand-drawn feel.

And Chashio, I know what you mean about the city on a slant. The Bridge of Birdseye is relatively flat, but the rock is meant to be really steep. If there are any Sketchup jockeys out there who know how to make terrain in Sketchup, I'd really appreciate some tips.

To give an idea of how steep I want parts of it to be, the look I'm going for (with the edge of the rock, anyway) can be seen in Cuenca, Spain, and the diaojiaolou style of architecture in southern China. If you're interested enough, check those in Google Images to see what I mean.
