Great illustration, Dan. Imagine the the working condition for the builders. :)
Excellent illustration! It is perfect for a SF idea, and I'm sitting here imagining what it would be like to be up in the tower, perhaps eating dinner, and looking out into space that way and back down on earth.This seems WAY luminous for colored pencils. Impressive!
Great take on the topic! Beautiful! I love how the surface of the earth glows!
