Children's Artwork Display Solution

When we did our house addition (expanded family room and eating area) we turned our dining room into a playroom and have been very pleased with this decision. There wasn't a lot of available wallspace in the room as it is open to our "formal" living room but I did want to find a way to display some of my children's artwork. The only space available was a five foot wall above the piano.
It was the perfect length for a small curtain rod. I purchased this rod and the ring clips from Target. It is the same rod style that I used for my dropcloth drapes in another area of my house. My children are thrilled to have their artwork up and I love having it up. I know some people use art display systems from Ikea or Pottery Barn, but I don't live near those stores--plus this rod was very inexpensive and it matches (in color and general style) the curtain rods and chandelier that I already have in this space.
Yes, the rod is centered on the wall--it is hard to tell, but the wall turns a corner just a few inches beyond the piano. If you look at the trim along the floor, you can see that it is farther back than the piano. I'm still deciding whether or not the rod is too high. I like that the artwork is high enough that the children can't tug on it, but I'm not a huge fan of the empty space below it. I'm still pondering this one.
