It's an impression of John William Waterhouse's "The Siren" (1900). Very nice. Water themed art goes well in any bathroom. The vivid colours in yours look better than the muted colours of an exact copy of the original would.
How wonderful to have a bathroom decorated with art! One of those things that makes life that much more enjoyable. In the states I had a grand huge bathroom, as everything in the USA has to be gigantic. It was fun having wall space for photos and art. And space to enjoy.
lol You might want lower the picture then just a bit, you should never have to actively look up while viewing a picture on a wall
That's my painting you stole it from me.................you gave me that painting.when we went to South America on vacation! Don't you remember.........................?
