I really like the idea of this assignment, I must say. Makes you look very carefully, mostly so at details, and looking "with the frame in your mind", which I like so, for many of these things would otherwise not have caused any interest in anyone ever at all. Very good. I might try to do the same just for the fun of it because it fascinates me so.
And I really like how you solved the assignment. Lovely collection, very nicely put together ... Yes, I like it a lot!
