Oil paint appears to be worked in smooth layers here, with blended transitions through the horse's flank and finer strokes picking out the mane, foam, and spray. The title Horse At Sea fits the handling well, because the water is described with loose white flicks and pale turquoise passages while the body stays softly modeled and solid. Blue, aqua, white, and sea green carry most of the image. Darker bands at the horizon and in the clouded sky hold the lighter surf in place, and one long stretch of deep water gives the brighter splashes more force across the lower half. A white horse stands in the shallows with one foreleg lifted, its head lowered and turned slightly inward. But the animal doesn't read as tense, since the curved neck, relaxed ears, and soft eye keep the scene gentle even as the water breaks sharply around its legs. The figure sits to the right of center, leaving room for open water on the left and a low horizon behind it, while the mane, tail, and spray push pale movement through the frame. The strongest fact is the white horse rising out of bright foaming surf.
