I used the linear fluid painting technique with tones of blue. The camera captured the blue a little bluer that it should be so make sure to look at the other picture. This was done on acrylic paper and is sold framed. The thickness is that of cardboard so don't be fooled by the 1cm in description. It won't let me put less than 1cm.
Such a wonderful add to a bathroom wall in my opinion but of course we all see things differently.
