And yet, one would think that someone could apply their knowledge of pixelling that they use to critique to the process of creating art, making themselves better than the commented.

You know, i know an "poem" in Poland, in which is:

"Komentujący nie musi być lepszy od komentowanego"

What mean sth like that: Comenter can, but not must be better than comented.

why dont you go work on your own art work before you go bashing someone elses?   when you perfect your pixeling abelities, then you can offer some info on how to better someone elses...
