I think creating self-portraits is a difficult task because you know yourself best and will always find something not quite fitting. But Leandro Leijnen made a really well-done 3D recreation of himself in a style that reminds me of How to Train Your Dragon.
Moreover, he built a whole story around the model, combining it with Pokémon. In this piece, Leijnen tries to catch Poliwag but gets soaked instead.
