I agree, some proper cloud formations would be a good start. At the moment Cliffs of Dover is behind the times in terms of cloud graphics. I'm afraid that once I get over the new colours and sounds, it will be a big sticking point against the game for me.
I know there is alot behind the scenes thats turned off until its finished but it'd still be nice to get something in the meantime to help boost the game's visuals to today's levels.
