Your not only straighening but also lightening up the whole thing makes the other one look less gloomy, much lighter and almost etheral, but as a tree with clouds behind is not gravity-bound in the sense of water with horizon and reflections or classic manmade architecture basing on straight angles, I think the crop with the diagonal tree here is just great, especially the suggestion of the weather exposure in dark version makes it indeed even better with a slant.
They are just very different moods created with simple changes, but both feeling right.
