Hi, I've gotta nit-pick you a bit with that first panel. With a crescent moon you wouldn't be able to see stars or any other objects in the darkened portion of the moon. The third panel looks better, tho. Sorry, I get the same way when sci-fi movies portray sound effects in space (space is a vacuum...compressional waves...don't get me started).
Anyway, this looks promising & I like the artwork. Except for the moon thing, as I mentioned, therefore, I have to give this one a '4'.
