Point taken about the angles. I didn't even think of that before now. As regards the light source debate, I think its safe to say that in maps that are used as backdrops for fantasy worlds where mortals can cast mind bending spells, dragons live and every woman wears a D-cup, one can overlook a little unrealistic lighting.

The problem becomes particularly acute when maps (like this one) are designed to be used with virtual minis in a virtual tabletop who represent characters that invariably bring their own light sources into the darkened chambers, not to mention the few that have darkvision. The lighting challenges are simply (in my view) too immense to recreate realistically, so in exchnge I bleieve one should just go with a little atmosphere.

Thanks for the kind words, they are much appreciated.
