This is great! The floor is very well done, with the light leading us into the frame. Funny thing is it reminds me of John Sargent's famous painting "The Daughter's of Edward Darley Boit" (if you've never seen it, you can see it at: http://www.jssgallery.org/Paintings/Daughters_of_Edward_Darley_Boit.htm

Sorry, didn't mean to be strange about it. What reminded me is the large, flat area of floor which becomes itself part of the composition, and then in Sargent's portrait he places the children in an interesting relationship to each other within the pictoral space -- with a good deal of separation and not in conventional poses. The same with your cats. They are in the same space and obviously have some sort of relationship to each other, but they are also individuals within that space. Well, my comment no doubt sounds rather pompous and I mainly meant it as a compliment to the way you've seen the picture as a challenge in spatial arrangement.

Well composed, and like the nonchalant poses of your models!

Beautiful shot - I also see the resemblance with the painting GJC mentioned. For me, it's the cats' white chests which look something like the girls' white pinafores.
