22 x 22"
Special thanks go out to Paul Kratter on this one. His discerning eye made me pay close attention to those balls. Remember: no matter what angle you're viewing a sphere from it's always going to remain perfectly spherical. So, at the very end of painting this one, I went back into each ball and drew a compass over each one. Sure enough, most of them were off by less than 1/16", but it was enough to make it feel off. I readjusted each one and that helped to make this feel more convincing. Thank you, Paulie!
