Make sure it is the first sentence of you intro.....and tag your photos critique-me you should get a few from that. Mostly I just degrade myself in the photo caption and people agree or disagree with me!
If you tag me in the comments. Will get a notification ans come along and comment. If you want the general people I would put it in the please critique in the first two words, that way people will see in when they are browsing.
Tagging them with "Critique-me" seems to do the trick for me. :)
