Hmmm if I were to turn you into an "avatar" or "OC", I would visualize you as a pink mori girl fox or wolf girl version of one of those ball-jointed anime doll things, but also with moth wings. Holding a steamy mug of hot chocolate in a pair of paw gloves. Setting-wise, your avatar would be living a sort of mixture of garden and computer lab.

I think three main concepts I associate with you are "nerdy/fluffy/warm". Primarily cause your hobbies I see are in sewing and baking, but you are also into tech, modding, gaming so that factors in. That you're into retrotech as well factors into the "warm" because for some reason retrotech gives me a warm feeling to look at.
