This is the third wall of this large mural, the back wall behind the tub and below the window. There will be some of the wavy water stuff over the window, but no fish up there.
Here’s the second side wall of this three-wall mural. It featiures a great white shark, because the client once went diving with them.
Here’s what the mural looks like in progress. In the first shot, you can see the image drawn on the lower part of the mural. In the second shot, the top few rows of tiles are on the glazing table being painted. I was part way through painting the background color on the roof tiles when I took the picture.
