Very interesting perspective! And I like their relaxed expressions - I could really use a nice hot bath right now myself. (Although I have to say that I have a feeling this might not be so comfortable for the one at the bottom.)
Oh, you know what this picture reminds me of? For some reason it reminds of another picture that has always come to mind whenever I heard this one phrase from a song. The song is called "I'll be" by Edwin McCain.
"Rain falls angry on the tin roof as we lye awake in my bed."
I bet the same picture comes to everyone's mind when they read that. I think it would be neat to see that become an actual picture.
