These a pretty good man. How are you shooting these? They digital?
I like the first one, it has a good quick first read, although what keeps us interest for second? The cement railing, or median, is divinding the frame right in half and that really seperate the top half from the lower half of the frame. In other words I would try to avoid a direct split frame as it tends to seperate the compostion.
The second one isn't doing anything for me. When ever I press the shutter I always ask; 'Will anyone care?' Nothing wrong with the composition, it's just boring.
The third one is really nice, good range of values, good foreground middleground and background elements and good composition. I like how you captured that woman mid-stride and framed her inbetween the edge of that car and the edge of the frame.
Be careful on the third one though, there's a pretty strong tangency at the bottom of the frame int he lower left, where the small car's tire gets really close to the edge of the frame. Your strongest forground element should avoid tangencies, because that is where your eye will focus and stay.
The third one is interesting, I love long exposures and 'camera shake'. Again watch splitting the composition into 1/2's, the rays of light end exactly in the cener of the frame, think of the compostion in 1/3rds instead, with your main focal points starting from and aligning on segemented 1/3rds of the frame.
On the last one, I ask; why? I am curious what you were trying to represent in the image. Usually slow shudder give us a feeling of speed, urgency, things constently in motion, but you have shot the picture contained in the frame, which "freezes" the movement. So I am curious what your idea was when you saw this.
Overall good set, keep posting, I really think the last three show alot of potential. One thing that I should mention, on my monitor the values seem a little 'flat', a small increase in contrast would do the pictures much more justice and give them some 'pop' value for the eye.
`What sort of people live about here?' asked Alice.
`In that direction,' the Cat said, waving its right paw round, `lives a Hatter: and in that direction,' waving the other paw, `lives a March Hare. Visit either you like: they're both mad.'
`But I don't want to go among mad people,' Alice remarked.
`Oh, you can't help that,' said the Cat: `we're all mad here...
