Very peaceful image. The brush strokes in the sky give it a great sense of depth for me, and the colors are well chosen. I can't help but feel like you could get away with rendering more of the waters surface, showing light caught in the ripples of the water and little distortions in the reflections, without betraying the calm tone of the overall piece. But what I really like is the character in the man-made shapes of the imagemakes it feel more like a real place to visit.
