I'm American and used to live in Cairo. :)
The bedroom looks spacious and nicely furnished, and if they like contemporary style they should be pleased with it in general. I think you should be prepared to change the artwork if necessary, depending on their taste. I would also hang it lower so that the center is at eye level when people are standing. I personally would not want the TV so high, as it seems they would be viewing at an uncomfortable angle. But I wouldn't have TV in the bedroom at all, so your clients need to make that decision. Good luck with your project!

Thank U! :)
actually I don't prefer putting the TV in the bedroom but my clients wanted this I tried to convince them but they told me it's ok to use it there

I think the art work is hung way too high and I agree the T.V. is too high.

which art work ? u mean the one beside the bed ? on the left it's a window and I can't change its height so I thought of using colored glass for the window and on the other side I used that piece of art to make it connected somehow!

How big is this bedroom? It's very nice.
