Just a passing comment, Alex. I'm loving the artwork you're posting, but there seems to be something missing: dirt and grime. For instance, that ambulance above doesn't look like it's suffered the effects of 80 years (or even considerably less) of weather and acid rain. The colors are still too brilliant and unobscured. I love that there IS more color on screen than what is shown in most post-Apo games -- those all seem to blur into a flat mud-colored palette that puts me to sleep when I'm looking at it for hours on end. But I'm certain that here and there, there would still some intense colors that pop out and smack the viewer right between the eyes.
