Nice, the only upgrade I can think of, and it can be done in the future, is to turn the wall into a piece of furniture.
Depending on how the rest of your house is finished, I can imagine the wall being covered in a wood veneer, perhaps with a grid pattern for the seams, trim and or reveal joints.
The wall could have also use different materials, frosted glass in areas, perforated metal or even padded fabric.
I think the rounded edges are a good idea. You might want to consider rounded edge beads from Fry Reglet or others.
