I'll probably work on this project for a couple more nights, but I'm close to calling it finished.
Planning to add an additional rim light to the top section of the right cello to help differentiate the neck + scroll from the curtain. I also need to rework the curtain model, it keeps coming back out of Marvelous Designer triangulated which is what's creating odd ridges when subdivided. Or I guess I could just not subdivide the curtain...
