I think you did a great job and all that I can see is that you need to preview the top with the blocks moved around.
If you have a digital camera take and move the blocks around and after each move then take a picture. After you feel that you have done all the different configurations that you feel possible go back and look at the photos and see which appeals best to you. Taught this in classes when I was teaching and all my students loved the idea as they could never seem to remember from one move to another. Good luck and I am sure that she will love whatever layout you choose
