While I would like to see a higher critique to art ratio it's just not really the nature of this forum at present. Even the most accomplished artists here often have to post several pictures before getting any feedback at all, and, unfortunately that can be very discouraging. The posters here on the Newgrounds Art forum are, generally pretty new to art and are not prepared to really give good criticism because they havn't had much experience with it, as opposed to posters on a more professional forum such as ConceptArt.org where good, thoughtful critique is given.
...BUT, I'd like to say that the feedback here is better than a place like DeviantArt.com where good critique (at least on the art pages, I don't know about their forums) is nearly impossible to come by.
I guess what I want to say is that users here are more unsure about the critique and comments that they want to give to other artists are so they generally keep their comments to themselves. At least that's the impression I have. =\
