On one hand we have to juggle humility in the face of freely offered works, on the other the stand-over demands of some that their works DESERVE acceptance.
One thing EVERY wall moderator would love to see is 'diversity'...creative innovation and imagination when it comes to walls AND skins too, for that matter.
Too often we receive in either field 'same old crap but bluer' described by the author as 'refreshingly different'...
Please!
It's never particularly clever to underestimate the moderators' intelligence...
Some artists confuse quantity with quality, assuming that if a million items are submitted then the law of averages applies and a number of them will get through. I rather see it as if there were ONLY ONE work submitted by an author then it alone has a higher likelihood of acceptance...so he at 'least' has one work 'up'. Flatulent spamming of the submissions runs the risk of people reacting out of sheer frustration of seeing more of the same and rejecting them ALL.
I think everyone would agree there are more than enough sea/mountain/sky terragens [for example] already...and what we 'should' be looking for is truly innovative permutations of them in future rather than just accept them because they are as 'good' as ones we have already.
Think of the wall section in particular as a 'communal library'.....where each 'book' adds to the appeal and diversity of the whole. It doesn't matter how fantastic Tolstoy's War And Peace is...there is only so many copies of it you can have in a library befor you start looking like a book wholesaler.
Creative diversity, peeps...that's what is needed...
