Kitties in the Window

I'm working on a mosaic of two kitties sitting in a window looking out. I'm still not sure about the background and sky. Are there hills? Is it night or day? Should there be a sun instead of stars? I'm using Mexican smalti. I cut the two kitties out of a trivet with my ring saw. And I like the millefiori flowers in the grass.

We'll see what happens next!
