I'm glad you got something out of my review.
Yes, I'd say getting that curved glass will be the tricky part for your project. Maybe you can find something already formed to cut to fit, like a plastic bottle... ???
The outer edge of that curved glass pane in Nighthawks is the only actual glass piece rendered in the painting, and Hopper cleverly involved it in an abstract composition of shadows and highlights in the window across the street. Very clever.
Oh, and when I studied Hopper in school I looked at a lot of his sketches and drawings... He certainly had his talents, but hands and feet were not one of them.
