I would much rather get critique from people I personally know have experience, knowledge, and ability that goes beyond a post count on some internet forum.
I wanted to create a portfolio last year and I asked an experienced friend to help me. Among my 50 000 photos I brought to him my best 14. He looked into them and after 2 min he asked me if I have some more. It took me two weeks to shake it off.
What doesn't kill you makes you stronger. If you want to advance in photography you have to be able to take critiques. Just be ready, remembering that you cannot please everybody.
I like the idea of having a special thread. Whoever puts something in there will be ready. I could learn from people critiquing others. When I am ready I would drop some of mine as well. I need just to import some strong stuff from Africa first.
Maybe we need some sections, something like for advanced and newbie, or tough guy vs Mr. nice guy. Just a thought.
I promise not to critique BIF nor Air Show. I have no idea how to shoot those, among others.
