Galen Ciscell, designer of Atlantis Rising, shares some lessons learned about working with a publisher on his game’s artwork and components:

If you find yourself doing the art direction for your game, know what you want ahead of time, communicate that clearly to your artist both verbally and, if possible, visually, and work with your artists from the beginning to realize your vision.

Be willing to adapt and experiment with new ideas you hadn’t considered. Publishers and artists know the business and know what is doable and what could be improved!
