Just an idea I get the most honest feedback from the chatroom. they will either post it in your comments, or tell you directly in the chatroom. Also, when I look at someones image, and see something a little off, I will IM them instead of posting in their comments. I do this because others will read the comments, and it immediately points out the flaws to others. I have noticed (at least on my images) that it sets a trend for a downward spiraling of negative feedback. After a while it gets repetative, and sometimes downright ugly. A little consideration among members would eliminate the need for the checkbox or a critique forum. anyway, I do still post comments and give excellents. Artwork can still be excellent - even with technical flaws. It's ll about how the image makes me feel when I see it.
