The Lens And I: Night in Theate Land

So this is my first shoot at night with my DSLR.  The last time I did a night shoot was with my iPhone (check it out here).  Again it's with my 50mm, and played with the wider aperture, however it didn't work right.  In the near future I will have a go in low light situations, so if you got any suggestions, give a shout.  I did go to Piccadilly Circus, but ran out of memory, but will visit there in the near future for a night shoot.

Anyways, tell me what you think.
