character for a video game

I want a character for a Ren'Py type of game. That means the character will not be animated, but we should have 3 options of facial expressions. The chosen candidate will probably be requested to provide additional ones in a future project (1-1, separate from the context)

The character should represent an adult who works in an office (not necessarily heavy corporate environment). There is no strong requirement in terms of gender, age or race. In a later stage we will expect additional characters (again, out of this context, in a follow-up project), which should reflect the diversity of the working population.

The character should not follow the manga esthetics usually seen in those games, but rather a more neutral and relatable style. The game will be addressed to mixed demographics in an European context.
