Hi Mike, some good attempts there. Some constructive critique though as well:
The first is a decent capture of a street scene although nothing exceptional leaps out from the shot.
The second is a strange angle which neither captures all the bridge or captures any specific aspect sufficiently and so it doesn't really work.
The third isn't straight, is very underexposed (too dark) and blurry.
The fourth is much better although the bridge is not sharp suggesting you didn't get the focal point or aperture right, or you had some camera shake.
The fifth looks like the focal point is on the man in the centre which if this is the intent is ok, but he's too far away to be the main aspect of the shot. If not then it's the same comments as the fourth shot.
How did you set up these shots i.e. tripod, camera settings, focal points etc ?
