I assume that your critique is very good. I wonder does it always need to be so constructive anyway? Heh, I tend to use a lot of commenting with one word and I really mean if something is 'wow' or 'awesome' because there isn't anything else to say. :3
One other thing that makes me uncomfortable is that I am curious about what people thin about my artworks. Even it is said with one word it counts a lot than being fully silence.
