How many times have I had my portfolio reviewed? Many many times. I once had my portfolio reviewed by Bert Fox at National Geographic. He kept one photo and told me to start from there. Of course while working on a Master's degree at Ohio University my work was reviewed daily.
When people ask me to review their work I know they may go away believing or not my edit. The best advice I can give right out is to edit tightly. If the photo is weak it is what people will remember. Be without mercy on yourself when editing or better yet, have someone you respect give you an edit.
Photo taken with a lensbaby in Eugene Oregon during a small Occupy Protest. This dog was by far the most active member of the group.
