Thank you for this thoughtful commentary!This kind of perspective is technically probably called "four-point" or "five-point perspective", although I didn't perform any construction but simply "eyeballed" it for the desired effect. I really love this exaggerated curved perspective with things swirling around the focal point.Roughness is mostly a result of this being painted in such a short time for the challenge. But so many things that you have mentioned happened to come together just right in this piece.The truth is that I am only beginning to look for a style and technique to make my own, so that each new work is quite different from the last. I'm really glad you enjoy looking at this otherwise daunting process.Cheers!
