I like how tall you made him here, it looks very stylistic, it's good you use more creativity freedom with his design. I honestly don't like it or Dianna to be honest, it's mainly their eyes and outfits, just since they look super ordinary and have nothing that really separate them between a Vocaloid and an OC. Also yeah Jinx is an UTAU so he has more of an excuse lol, besides I'm not selling a product.

The outfit idea is interesting, it's sort of halloweeny because of the rips, the crown plus the rips make him look like a toy.
