Myself and Tillerz both build character sheets on the World Anvil World Building site.
Some examples below:
Tillerz Sheet List
Graylion Storyteller Sheet List
This includes the following 2d20 TTRPG games
World Anvil has over one million users and we want to make sure they have Dune Character Sheets available. They are available to any World Anvil users to make characters starting with free accounts as there is no charge for the sheets or the use of the sheet within World Anvil. Once completed the sheets will go out as announcements in the World Anvil Blog and Discord channel to users, as well as being added to the community character sheet section.
We both passionate about Dune and agreed to collaborate on the Dune character sheets. We plan to release the preview version and update them with the final release once available. We are humbly requesting any fan-use logo or art assets that we can use to make the Dune Character Sheets even better.
Thank you for your review and consideration of this request.
