V1: Not great
V2: Kedarui Aashii, blue eyes, smile, open mouth, scrunchie, laidback smile, nikoniko
V3: Hair seems better, default to side ponytail without changing to a specific hair style
V4: may not be better than V3, trying to fix the pink iris, CFG < 4 (?)
Edit: Turn out it might because of her hair clip and facial mark that sometimes she has pink heart-shaped iris. I can't fix this. So V4 might be worse than V3.
