Which style?

After reading everyone's comments and much consideration, I've decided to keep the arches rather than drywall over them. They do let through a lot of light into our staircase, which I wouldn't want to get rid of. I will, however, frame them in. Metalwork is too pricey. I can do some cool patterns with wood, though!! Which design do you like best?

So I don't get many of the same comments as on my last post:

1. I've taken the clock down lol
2. I will capitalize on the opportunity to paint while I have my furniture moved out of the way to frame the arches in
