They are OK as snapshots, but that is it. They have no interest to people other than you and the people in the photos. Not trying to be harsh, but that is the bottom line with much of the street photos on the forums. Esp the ones that show a bunch of people on the street as a mishmash from far away and have nothing going on interesting. But, one guy said the same thing of my work saying nothing interesting in them and I should trash them all - so it is hard to argue taste.
I'm glad you are trying. I am not much of a landscape person. I prefer people pix. Seldom see good street pix here.
Here is a thread I started about AA. He was a crappy street photog.
http://www.fujix-forum.com/index.php/topic/28923-ansel-adams-wasnt-much-of-a-street-photog/In the thread I show one of my street portraits shot with a 4x5. I had to give up on the view cam as it made pretty boring street shots. But still, my boring street portrait is much better than Adams street crappers. That shows you the difference between a high level landscaper versus a high level street photog. Sure, AA can out do me in his field, but once he comes into my field he is nothing.
I don't know how to tell you to do better. Look at lots of street work and learn from it. If you don't know the good from the bad with street you will never be able to do good work other than by accident. Maybe stick with landscapes or such if that is the case.
Here are sample from the latest artists' book I shot a couple months ago. This will give you a flavor of where I'm coming from with street candids and street portraits. (posed)

http://whoopwhoopartistsbook.tumblr.com/The bottom line is you should try to make photos that are interesting to a wide range of devotees of that genre, something that they would like a print of or to save the digital file to look at again. And if not, try to make something iconic where the person seeing it will remember it even if they do not like the genre.
Good Luck!
