Since the grfx world here is so dead i decided to try them, to see how well my photoshopping skills stand....
I submitted 2 pics in cheasy competitions - i got D- and C+ so far
but so far ive worked out that
-Submt your picture at the last moment - cause then it gets put at the begining of the list of pics - people are still enthusiastic in the begining....plus if someone has done a similar idea..which may happen (of course)...yours will come first.
-try to make your pc longer than wider - since they have a 500pxl width constraint but not on hight - hence you pic will be bigger (detail) in "preview" mode
i just started tere 3 days - man its complicated and competitative.
