I'll talk to the artist about a player sprite.
In your mind, should there be a choice between a male and female player?
I think it would be ideal, as I don't think anything in this game suggests the player could be only male or only female, so having both is best.
If I had to pick one or the other, I'd maybe lean to male, just due to that being more of the standard/default in these kind of games over being only a female player.
