Nigel, I'm very, very impressed. A very brave choice on the colours - I would never have put them together. The dado rail and fake woodgraining look especially good. You must have the patience of a saint to do that!
Ooh! You could do a Peacock Room! Blue and green silk Morris weaves, and stencilled peacock feather friezes, and jewelled lanterns, and probably somebody smoking a hookah on a gorgeous carpet, or just copy Whistler's!
By the way Nigel, this wallpaper for the ceiling somewhere is something I've been meaning to pass along: http://www.ornamenta.co.uk/site/html/sub_wpapers/hp_clouds.asp
