I really like the idea and the implementation, it looks really good. Anyway I am not sure if it is a nitpick but one tree in the left looks slightly bent while all other seem straight. This isn't bad, but if it is only that tree it makes the effects in the image feel inconsistent. It feels either more trees should be effected or either it should be shown betters why it is just that part of the image.
I don't feel the cyclone part of the image was showcased great, it doesn't feel that dangerous from the art. Anyway that were my negatives, the art is great and the idea is really well, could work for a small indie game premise and would make a great cover art.
