Frankly, I'm not a big fan of street shots, but I do like CNXT0081~1.
The problem with Yahoo photo albums is that you and Steve get to see the full size pics, but the rest of us don't. If you put some pics in the files section, or send them as email attachments like Steve does, then the rest of us will be able to properly appreciate your photography.
In shots where the background (such as sky) is brighter than the subject, it helps to turn on the flash, even on a sunny day. The flash helps to fill in the shadows and, if the camera is aimed at right angles to the hair, the flash will bring out texture and shine in the hair. And with street shots, you usually don't have to worry about the flash causing red-eye.
