alright guys, I need your help

So as some of you may know this is my OC that i made with possibly the most simplistic design possible, a cat/fox like creature with brown fur and blue eyes, obsession with coffee and a calm behavior. Well due to his overwhelmingly simplistic design I feel as if he needs something more to him, I am asking for suggestions; whether it is accessories, or adding a little design on the fur.   (without completely destroying his simplicity) just something to give him a little more flavor
