My day job in fast motion.
Here's a time lapse I did a while back. Thought it was fitting here in the art section.
This ceiling is roughly 16 feet by 14 feet in size, and the center of the ceiling is about 17 feet high. I actually painted this ceiling twice because the original owners sold the residence and the new owners wanted a new and different mural in the space, about twelve years apart. A master sketch of the whole ceiling was created, and then each main detail was sketched a second time as a close up so I knew exactly what was to be painted.
