The Palace of Earth Spirits as seen in Touhou Mecha. Touhou Mecha
is a visual novel I made based on Touhou Project's Subterranean Animism
Figuring out how to light the place up was the interesting part. It's the underground, so it's going to look like it's nighttime all the time. I didn't want the place to seem too gloomy, so the color gets fairly rich in the shadows, but becomes pale in lit areas to make the lighting seem strong. I looked up cathedrals and some government buildings seen at night for reference, including the White House!
