After failing miserably in my attempt to finish this map in the latest Lite Challenge, I'm setting up a thread here so that I can keep working on it. Now that there's no pressure on me, I'm going to take my time and redo the bits I don't like. I'm hoping to put in a few hours over the weekend and will post an update soon.

Do you guys have any tips for working on huge images? I'd like to make a big image so that I can include lots of detail that gets lost if the image is only around the A4 300dpi print size. I'm working primarily in Inkscape, then I export into Gimp so that I can add shadows or distress some of the buildings. Right now I've got about ten layers and already Gimp is starting to slow and takes a second or two to redraw the image and it's only going to get worse. My computer maybe isn't a rocket, but it's an i7 with 16 gigs of RAM and I run Ubuntu, so the OS isn't hogging resources the way Windows sometimes does, but I'm not sure how best to approach this. I'm thinking of working in sections, like maybe working on a quarter at a time then putting it all together at the end. (This is one advantage of a geometrically-shaped city!) I just wondered if those of you who deal with this sort of thing on a regular basis had any tips.
