I think its your best version of the water, and I like this color. The gulls work but Im not personally struck by any symbolism on their part, I think the painting could take or leave them.
the left side is a little darker than the right, is that just in the photo?
the lower clouds that dip down directly to center I normally dont like but for some reason i like it here. The part that im not sure about is the stuff above that.
those clouds, compared to the rest, look like brush strokes sort of going straight out, and altogether around in a circle. Its not bad, its either a clash of style or just my taste.
I like everything below a lot. I am seeing that water as night color, imagining a full moon and luna halo. So I might be mixing up the intention of day emerging and seeing it wrong.
Its a lovely painting, quiet and strong, and works in different ways depending on your mood.
