A very good summation of important things to remember when giving or receiving critique Asa
Some technical data would perhaps also be good to provide: Camera, lens, focal length, flash, hand held, tripod, f-stop, shutter speed. In some cases this will make it easier to make suggestions. For instance maybe I want more depth of field in an image, but was that even possible for the photographer? Or if an image is a bit soft it can be good to pin down the issues to either shooting technique or perhaps only more sharpening would need to be applied on the final photo.
Regarding color and similar I'd like to remind everyone that one really needs to have calibrated monitor to judge this correctly and also either a color managed browser or download the image to a color managed program and view them there. However for copyright issues the last approach is questionable. Personally I'm in the process of moving everything to a new computer, so color issues comes painfully obvious to me today, so will not comment on color until I get this sorted out. Also it would be best to convert all images to sRGB color space before posting - but most will probably use this from the start anyway.
I'd also add that one of the scariest things may not be to actually post your image for critique, but it can also be intimidating for the one commenting! Especially if one is new to the area! So in particular I'd like to welcome all brave comment givers!!!! Commenting is very educational also for the one who comments, but it can also be very time consuming. Always keep this in mind and think about critique as a gift. People do this to help you, not the other way around!
Also I think it can be useful to indicate what level of critique you want. Not everyone will know your shooting style so if you are a beginner or an experienced photographer you may want/need different levels of critique.
