Sorry but I think it isnt crooked. Take a window and move it so the water line is near the top of the window. You will find it is parralel. I think it's an illusion. the mountain on the right is farther maybe it's that.
It's about .5° leaning to the right... so, Harmony: it'll only dribble out onto your desk (or mine, for that matter ) and not rush, but other than that it is very beautiful and makes me grateful for the new soft, warm sweater I got myself today, for otherwise it would make me shiver with cold just from looking at it! It looks quite cold. I like how landscape and sky blend into each other, for that is the true situation often with such very low hanging clouds.
