F2 and F6 aren't really too inspired (F2 looks more like an egyptian Bigfoot than an orang-utan and F6 looks weird)
F5 looks quite weird like a priest, a bit too western imo.
F1 is basically just the reference dressed up with some clothes and a shield.
My favorite designs up to now are F3 and F4. I actually don't know whether it's okay to show the nipple like this but the rules implied if someone looked over my shoulder and I'm not ashamed it's fine, so I think this level of nipple is fine. The way F4 holds her shield kinda doesn't make sense (since for the Baluse your hand has to fit in that round little thing) but those can be redesigned to a wrist-guard or something with similar sillhouette. I like the shape of F3 but I also really like the concept of F4, since my endgame is making a "Defending Guardian", making an "Ancient Orang-Utan Grandma which protects the young apes" really works well with the theme.
Going forward I will focus on the F4 design but I will have to figure out what to do with her hands.
