The under the bed one is a fantastic concept, and the composition and all the physical elements are great: I think my only concern is that the vintage effect contrasts unhappily with the very modern bedspread. The same pic, the same distressed texture but without the sepia toning, just straight silvered - or possibly toned towards the blue end - and grained to look like it was taken in low light would look brilliant. All totally my opinion, obviously, and therefore worthless.
The first one is a cracker: "Are you my mummy?"
