You may look into transparency/refraction/reflection settings to make the "cloud" blend into the background better. You may want to adjust the xyz scale of the cloud texture in the material editor. Perhaps look past the spaceship(perspective as it is - is odd. makes the cloud look small or the ship is emensely(sp) large - on a galectic scale). A good time to figure out if the spaceship or the "finger like clouds" is the subject of the pict. (good start.)
