Cool. May I ask if you have a time frame when a first version would be released? Also would it only include the portrait, or also a body with some clothes / poses? Do you have some other details you could share or even a discord channel where you share your progress?
Sorry but although I've been working on portraits for a while, a portrait maker asset is way too far out to give you any information. You're welcome to join the Discord (link on this page), but it's not something I talk about because it's not a currently active asset.
