Any pose idea?

I think it we be cool if you had lamb leaned backwards, in a almost crouched pose with her bow draw to fire, and contrast it with wolf leaned forward, just starting to pounce forward with his claws extended. I'll make a little drawing with it later

Since the character's appeal lies in the size difference, put them on his shoulder or carry them like in the image

an action pose with her boosting off of wolf with her bow drawn, wolf ready to strike with his claws. so that you have lamb mid-jump with one foot attached to wolf's shoulder (or wherever), if that makes sense

Since you modelled the bow too, maybe you should make her draw the bow "mid movement" to create a more dynamic scene. And Wolf could stand behind her, in a more protective pose (Edit: looking into the other direction) to cover her back? This could profit the "huntress / hunter" scenario, but I don't know if it fits the artistic nudity.

Something with wolf behind or above lamb
