If any of you are really interested in contribute to the game with pixelart and have some time, I would recommend to participate in the Contest "The Sick Tree"
http://forums.themanaworld.org/viewtopic.php?f=8&t=8883 , or send me a PM, we have plenty of work to do and we can share that work with you.
You don't need to be an expert, but you need to be willing to learn and become one, it doesn't matter if you never pixelart before, we all did learn on the road (there is no schools for expert pixelart). But is a demanding and rather hard task, requires patience and dedication. Also requires team work. But the door is open to anyone interested.
