This puts me under pressure to say something intelligent and I'm not always capable of that.
Aside from the harshness of the light, the overall impression I get from this set is that you aren't quite certain what is interesting or what you want to show us or how you want to present it. Thus the images may not be from a good angle or the subject may be misplaced in the frame or there is so much background stuff that is distracting.
Out of these I think that #8 had the most potential in the shot - a little girl walking down the street watching her fingering on an accordion.
The first three things I would have thought upon seeing her coming would have been:
- get in front of her and down so I could get something of her face.
- move over so I can get her against people walking normally (for the contrast)
- move over so the distracting bright patch isn't behind her.
(it is not unusual for me when I see a shot approaching, to retrace my steps quickly so I can get in front of the shot again in a place where I need to be to get the shot I want.)
IMO, the key to successful street shots is to manage the shot so the viewer is really, clear clear what you are showing and that the rest of the image does not distract.
Framing and position of the centers of interest is crucial so that the viewer is led to what you want him to see and gets some idea of what the photographer thinks is interesting enough to capture.
If something is bright or in focus or somewhere prominent, the viewer who is trying to decipher the image will try to fit that in the puzzle.If the center of interest is placed oddly, this will draw attention, even subconsciously, and viewers will wonder why. For example, in #4 & #7 the people are to one side, there's lots of space at their respective backs, why is that? Viewers have an unvoiced assumption that if its in the picture, it's because you meant it to be.
Go out earlier or later so that the sun isn't so harsh.
Try shooting at different levels rather than always at your eye level.
Just as target shooters do dry-firing (without ammunition) to practice a smooth trigger pull, even when you aren't shooting pictures, frame situations in your mind's eye for shots.
Get used to seeing things as compositions rather than a single object.
The more practice you get, the better and faster you will be.
Amazingly on topic, in the July 29th issue of Sports Illustrated there is an article about this very thing titled 'Talent, Practice and the Science of Performance' by David Epstein
Although that article doesn't seem to be online, a search of that title brings up several related articles that all say the same thing; in everything from hitting baseballs to playing chess, practice in a concerted way makes you better able to see and anticipate situations quickly.
After several years of practice and looking at tens of thousands of shots, I can get decent quality shots (exposure, focus, composition) much of the time; really good shots that have some impact, that transcend the moment are always, if not a rarity, then not common at all.
