Hey Pete, I just took a good look at your gallery and I wanna tell you that your work really inspired me. It sucks that Parkinson rang the door bell, but I think you should hang on and keep taking pictures.
On another note, I don't think that the tilting of the camera fits your subjects. I'd try to shoot straight and keep the vertical lines vertical or close to it. Angles are unavoidable, it's just tells us from what height you're looking, and that's fine, but when you tilt you should not forget that you're simulating how the public views your scene and it's not a very common way of looking at things, also not very comfortable. Some examples of what I'm talking about are "Big World, Small Kid" and "Train Dudes". Hope this is not an unwelcomed tip
Pedro
