In general

• Don't be afraid to show us your unfinished pieces, we are there to guide and help you through the process.
• If possible, hang around the #tmwart channel on freenode 24/7.
• When you're available / doing work on tmw related stuff, please contact me on the previously mentioned channel.
• We're soon going to have a centralized repository for all the art related stuff where we're going to archive all of your versions: so you can just start to contribute there without the need to track down a dev. The details on the repository and the preferred version numbering are coming soon. EDIT(20050419): Ask me for details, it's up now.
• Preferred formats: .png and .ogg

Concerning conceptual art

• You can always come up with new ideas to present to the team. Actually that's preferred and we like that.
• With conceptual art you might want to define important places, capture the generic athmosphere, look and color scheme of a certain place or define the looks of an important npc.

Concerning tiles

• We REALLY need a LOT of these, so if you think you can do ANYTHING, please give it a shot.
• Especially on these actively seek out our attention so we can assign new tasks to you. The fact that we won't contact you personally every day doesn't mean we don't need your efforts.
