I want to post about a different aspect of "improvement" - not the technical stuff, but the artistic stuff. In my signature (below) I have linked some articles I had published on developing style and mood in image making. Sadly the second one has gone missing from Steve Huff's site somehow but the other two are there. It contains some ideas on how at least I improved my own work.
I think it all depends on what you are setting out to achieve. And I suppose that means you need to have (or develop) a goal for your photography as this provides the means of measuring yourself against something that is meaningful.
As for me I adhere to a more artistic interpretation of photography and in pursuit of this, I try to live by a few simple things ideas photographically speaking....
1. I mainly make images I like - not so much what I think others might like. Though if they do its a big bonus.
2. I mainly try to make images that "grab the eye". To a significant extent this is about the "rules" of composition etc but ultimately it means having an image that is in some way beautiful and interesting. And ultimately that means developing an eye for a good image. If you cant see it you will seldom capture it - except through pure dumb luck, which thankfully also happens from time to time.
5. I treat my images as raw material. Since moving over to digital it has facilitated me undertaking post processing. My advice would be ever be afraid to improve images in post if you can. Even if you are shooting film you might consider how you can do this in a darkroom through enhanced printing. If you do not know how to post process - learn. The goal is to make good images not to be a purist and always do it all in camera unless you specifically are setting out to do that as part of your image making discipline. If shooting digital this probably means shooting in RAW or if shooting analogue it means scanning as tiff images as both formats keep more of the image information intact so your end result in principle can be better.
Here are a few examples from the street. Conventionally they would be regarded as bad photos (blurry, not sharp, too dark etc) but I like them as they capture a feeling. And if you work on the viewers feelings then as far as I am concerned that is probably going to be OK art.
