Apparently I am just a hard to please nitpicker! I did give it a 7, however.
Lol, I think you are. I thought this was almost perfect, I didn’t see any distortion at all. It’s so hard to get this right in camera. Let alone with corrective perspective.
There appears to be some minor but visible curvature from lens distortion. Other than that bothering me, this is a pleasing and interesting shot. Would make a nice desktop background.
