I keep on painting about water, in this occasion is on the beach and fishers pushing a boat at sunset.
The three seagulls, as you can see, is the most interesting part. One famous painter always paints several seagulls in his seascapes. I've adopted that design, but only with three seagulls. Three is a magic number in painting.
Well, this is a little joke, but not entirely.
There are others principles of design. Some painters think that unity is the most important. If you observe my seascape you'll see that the blue color is dominant, other design principle.
