Animals feeding does not really evoke "Intimacy" for me. But then again, I grew up in the city and this may be my own personal limitation. It would work for me if the lamb was cuddling down to sleep next to the mother. I think this photo would do better with a POV angle down lower - more from the eye level of the animals.
Good concept... it captures intimacy. The composition it a little haphazard... maybe s lower angle with shallow DoF, or maybe capture a close up of just the nose on the tail or baby's face. Lighting looks like on-camera flash which is a bit harsh.
