Source Photo ideas
this is a hybrid of a couple of the images. I can open up that sun moment and highlight the clouds in front and below it and match up with the highlight on the water.
and below are two new images I just found in my camera. boats/docks/reeds would all be elimated from painting.
This is the source photo that I used to paint the painting I put over your fireplace. Those land forms in the forground can be connected to create a form more indicative of the San Juan Islands.
This image has more of the blues at the top that you like with the clouds regressing to the horizon line. What I read as peach at the horizon could be replaced with yellow light.
This is more of a San Juan Island view (probably of Lummi) The cloud at the bottom may be heavier than you like, but I wanted to give this as an option.
This is where the cloud formation is less distinct and its more about the light behind and reflecting on the water. Again, the peach/pink could be replaced with yellow when painted
because you liked the above cloud painting, I found this example of clouds that could be incorporated into a pianting with land forms at the horizon.
