I took the next two photos to look at similar types of buildings, again with the spires. I like the rounded shape of the Westminster Abbey arches more than the bridge. The windows are again rounded at the top, and as they are quite long they will let plenty of light inside.
This figure is quite foreboding as it was part of the London Dungeon exterior, yet it fits in with the period and again has the rounded frame to it. I also like the lighting around the hood as it gives mystery to the figure.
Finally, this image was taken in Covent Garden at Christmas time when they had this light display. I really like this as it looks rather magical and would fit into the magical theme of a castle. The lights also moved so this could form part of the animation for my piece. I also like the way that it is lighter around the bottom by the normal lamps lighting the walkways and walls, yet the darker night sky is filled with the 'prettier' lights.
