It's a little funny. but it is still working in the capacity of a containing shape.I was thinking, bring down the top edge of the blue so that it makes a horizon behind the fish and cuts through the lily. bring the bottom edge up past the lowest petal. an amorphous shape something like that that suggests the changing reflecting water surface. so it would lay down as the water surface rather than look like a rubbed out view of a foggy window. I don't know, it looks pretty good any way.
