Go give the artist all of your money.
Artist previously known as Lolimoog who changed their name to Gloomilo for obvious reasons. They don't actually draw underage characters.
That said the model seems to want to make young characters so shove the appropriate tags in negs.
Steering out of the artist's regular subject matter will result in images that don't really match the style but they still have a style of their own. See the training tag counts at the bottom.
