This is beautiful. It's reminiscent of something I can't quite pinpoint. I get a vague sense of nostalgia from it, which probably sounds weird, but it's true. Mostly, though, your use of watercolor is amazing to me.
your watercolor work is all amazing! this piece stands out to me for some reason though. maybe it's that the golds are so warm and inviting? anyway i love the stylization of the horse and the colors you used. it's very beautiful! <3
