I think the clouds in the background should be in a more circular shape, as it is a background... well that actually doesn't really matter. It's just my preference. But I really do love this design :)
I agree with .onion on the clouds, besides this, maybe something a little less "regular" than black would be nice? Asphalt maybe? Other than that: fantastic! I'd really want it to get in the catalog, so it can come to Holland!
a different layout/shape for the hole in the clouds would be nice... as is, it's aaaaaalmost symmetrical, enough where it looks like either it's supposed to be and not quite achieving it, or not supposed to be and failing.
that said, everything else is enchanting! it's a minor detail!
