The color, the drawing and the rendering are superb, far better than I could ever do.
But there is something that seems off.
Look at the smaller building on the left.
The perspective seems off. The groundline would have to be curved in order for that building to be at that angle.
But, hey, this painter’s work is earning a shopping cart full of bills, and I haven’t sold much of mine ever back when I produced art.
It’s Venice. All the buildings are built on marshy islands........................
It’s on a canal.
Great eye. I think your point is correct, but I think he captured the scene accurately nonetheless. If you look closely at this similarly positioned modern photo, the porticos of the building are not level with each other today.
