I've tagged most of these personifications, but I'm not sure about the girl with the green hair and the samurai guy. Is it Yamatsukami and (Ashen) Lao-Shan Lung?

Yes, the comments on the original image identify them as such.

Now I really have more reason to love kushala daora personification *Nose-Bleed* and that mini Silver Rathalos
Is seriously cute

Yama Tsukami looks cute
