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.
• you can find the technical specifications of tilesets under Tileset development
• Please keep in mind that the mapper only got 3 layers from which 2 are under all moving objects and 1 is over all moving objects.
• althrough we prefer high quality tiles over low quality ones, please keep in mind that we try to reassemble the look of old SNES games. so please try not to make the tiles too realistic.
• All the tiles in a set needs some coerance:
  • The direction of the light (south-west for outdoor tilesets, diffuse light for indoor tilesets)
  • The perspective (45° view angel?)
  • The propotions (a character is one tile wide and two tiles high)
  • The color style
  • The tiles in one tileset should be able to be put together in as many different ways as possible to allow the mapper to express his creativity.
  • (Please add more guidelines)
