Excellent feedback from you all - thanks. The moon was moving so fast, getting to the bridge would have taken too long ...lack of planning on my part. Actually, I learned something about shooting the moon (never done it before) - I think I should have taken another shot of the scene by spot metering on the moon only, and layer it in in PS later ...I think it is way too bright as is ...Also, regarding the buses ...there were that many in a single shot, and that is really what I liked about the picture ....sort of London Rush hour craziness ...thanks to all.
