I suspect that the burial chamber's decoration is designed to look like a papyrus with scenes from the various books of the underworld on it. One of the "books" of the underworld found in this tomb is the Litany of Re; another was the Amduat. The photo above portrays a demon of the seventh hour of the Amduat decapitating the enemies of the King in the underworld.
The other photo in this post shows Isis, as a tree with breasts, nursing Tuthmose. To the left of this scene is a drawing of the King standing with a mace and staff in his hands (partially visible). To the left of Tuthmose (not shown) are drawings of three of Thuthmose's wives and one of his daughters. This particular scene is on one of the columns that supports the ceiling of the tomb.
