Sometimes you go to meet a friend whose train is coming into Grand Central, but you get there early so you have a half hour to make a sketch. Would love to do this view, in a longer sitting. The angle is so, so challenging! Also the light is always beautiful in there, even after dark, and the colors are fun to try and duplicate; there are a lot of subtleties and shifts.
*Also, unrelated, I just edited my "Troop 54" post to include links to the podcast of the play reading, so if you want to give it a listen, go to the post here and scroll to the bottom for the links.
