I think I can speak on behalf of the art forum when I say: Thank you, Radium, for all the good critique you've giving out.

We need not only to remember to credit each other for the artistic work we do but also the effort we put into critiquing each other's works especially when you do it as constructive as Radium does.

Some good examples of Radium's fine work are his artistic responses and in-depth responses.

From personal experience, such valuable critiques are a rare find and one should enjoy it to the fullest while it lasts. Most critiques on level with Radium's trend to be rash and very personal which makes a great difference, you should seriously consider becoming an art teacher or something in those lines.
