Red Square is actually a picture of St.Basils Cathedral which is next to Red Sq. At least add that as a type in.
Also Big Ben, although usually shown as this picture, is actually the bell, this pic is of Elizabeth Tower, or the Houses of Parliament, or the Palace of Westminster. These 3 should be type-ins as well
One of the problems I have with this is that the idea is not original at all, but there is no credit given. In fact, there is a featured series of this. Correct me if I'm wrong.

Good effort for one of your first quizzes though
