uhm i actually mean game design sooo the artwork for a game like pixelart and something like this :D
Viewing post in Where can I learn GameDesign?
So, how to make pixel art and/or art specifically for use in games? You should be able to get good advice, or at least useful pointers, on Open Game Art. Though many of the same people are here as well, so, maybe ask in the art forums right here first?
