Someone on the D&D 5th Edition Facebook group posted a link to these really lovely and very playable-looking 5e character sheets. The designer of the sheets, William Lu, posted them on ArtStation and writes:
Custom, combat-oriented character sheets for the Dungeons and Dragons 5th ed. tabletop game. Designed to be a familiar sheet for veteran players, while retaining its unique look and strengths.
Features a design inspired by Celtic interlace art. Incorporates the feedback from many hours of playtesting to make sure the sheet’s utility matches its beauty.
You can download the 7 pages of the character sheets here.
