This has come up a few times over the past couple of years that I've been popping into this forum. The general rule of thumb seems to be that if you want criticism, ask for it. I've asked in the past and gotten some really good feedback that helped to improve a couple of my photos.

My own personal rule of thumb, going along with that, is to remember to ask for criticism for each image that I want it for. My guess is that members won't remember my blanket statement in regards to wanting criticism of any and all of my work, so I try to remember to ask for it with each shot. While I could see that becoming cumbersome for people who post a lot, it works well for me since I only post a few times a year.
