The kitten should be cute but not childish, with a sense of adventure and personality. Around the kitten, small hand-painted decorative elements: paw prints, tiny stars, leaves, keys, mushrooms, ropes, little bones, coins and subtle dungeon-related symbols.

Include a small elegant title area reading “DONJON & CHATONS” near the lower third, integrated naturally into the Ver mais
