If you are going to have it on a bed the way the picture shows you could even go a little on the 'cute' side and frame the top with a "topper" like its a window you're looking out of, and do the bottom so it looks like the top part of a sofa with a cat laying on it looking 'outside'. Frame the sides like its drapes hanging or window trim and you've got an unusual version of attic windows....great job!
