though we already have two entries (it had been worse!), i'd like to express my displeasure over big-canvas challenges!
i see no point in forcing people to enter pieces with big empty areas just to fit the challenge rule. if they even enter. pixel-art is not about big brushes but about details, and this just takes time! time that weekened-warriors don't have then. so, unfinished pieces or half-assed rubbish makes up the numbers.
i've done dozens of pieces in the size of 320-by-something, mostly for demoscene graphics cometitions which contrary to the pixel-art scene are about 'resolution', not 'canvas' (e.g. 320x256 = Amiga, 320x200=MCGA etc.) but none of them was done in less than a week.
hey, i've tried something like this a few months ago, nothing beyond a few sketches though. that challenge seems to be a good reason to resume that endeavor.
still have to do something else at first.. or maybe i'll cut some corners and pixel a panda on a radio tower =P
