I simply take images for enjoyment and only toss my hat into the comp ring to see whether it may be picked up, hence totally agree with Marc...it's too much like hard work to beaver away with the intention of creating a "winner" (...it only leads to disappointment and going to the Dark Side of the Force
)
I also have to wonder about a comp that requires you to use brand-x or be part of some clique to be eligible to even enter. e.g. I can't imaging Wimbledon disqualifying entrants who don't wear Nike runners or are not members of the local strawberry pickers union (though the Wimbledon strawberries are quite excellent
. )
As for this comp...Yeah,nah. Not for this little black duck.
