I quite like the battlemap with the clouds. I'm even pondering the idea to create one without the clouds as DM/GM version for if the player characters go exploring.

The second map, I have to admit, I am not too sure about it is about, or what is happening. The name doesn't hint at it. But, don't get me wrong, mystery is awesome, though adding clues would help in figuring out the map(as a viewer and a player character, unless the DM/Gm goes into explaining what goes on). Hope that helps.
