No Turning Backby
KaDiComment: In respone to the brutally honest obsolete thread here is my hopefully constrcutive critic...
First thing that i noticed was the wierd lighting.. seems like your white balance was off, and you were mixing two types of lights which further confused your camera (seems like blue light coming from the left and tungsten light from the right)... also the image quality seems really bad.
Looking at the photo info i think i can immediately pin point the problem, you shot at 8 seconds exposure! Assuming you used a tripod and a remote to remove any camera shake it is really really hard to get fine detial from such a long exposure if whatever you are shooting isnt producing its own light. Things to take at 8 seconds are city scapes at night, moving lights of various kinds e.g. moving car trails, moving water, mulitple exposures with strobes, etc.
Take the same shot outdoors in broad daylight and compare the two...
I would also recommend you read up on exposure, aperature, shutter speeds, etc. You seem very fond of using high aperatures e.g. f16 or f20. Using such high aperatures is not necessarily a problem but using them in the wrong situations is. Also do some research on the lenses you use, find out which aperature settings give the best results.
I think once you learn good techniques you should notice a change in your scores. Also dont be afraid to sit down and read your camera manual from cover to cover.
Good luck!
