Were you able to find a suitable shade for your door yet? Roman shades sound like they would work well but I'm not sure if they'll go with the contemporary/Asian theme you have...

I agree that Roman shades would be nice.

Another option is a simple curtain rod and curtain. This is what I have for my front door, and it works great. Put the decorative side facing out; make sure to pick something that would look good from the street. Add a layer of a simple white, ivory or another neutral color to line it on the inside for privacy. You can use curtain tiebacks so that you can see out during the day.
