Architecture Attempts...

Right, so. I've never really known what I was doing with architecture photography. I just point and shoot and hope it looks pretty... but there's always a window in the wrong place or a weird shadow covering half the building or a naked man on the balcony that I didn't notice until editing... you get the general idea. I had a go anyway when I was in London and got some generic touristy shots. Nothing that anybody else who's ever been to London won't have too, but it's a start. Feedback would be greatly appreciated.
