Dramatic clouds of the past storm look gorgeous to me. Together with choppy, but not too stormy sea, they make a dynamic yet peaceful composition.
I love how clouds look in approaching storms. There is so much definition you almost feel like you can touch them, like they are a solid thing. The colors in them bring a feeling of a cool breeze and the smell of rain. I also love the colors in deep water. Couple this with the clouds and it makes for a thick blend of color and feeling.
