So I've got this great idea in my head. I have concept art that took me an hour of honest effort to finish the idea but epicly failed. So here's my idea.

An aqueduct should be the background. If you don't know what an aqueduct is, you've missed out on a big portion of Roman history. This is the concept art:



Shitty? Extremely. You can see why I stopped. I tried to base the image off this flipped screenshot from Assassin's Creed: Brotherhood:



...except, of course, as a ruined winter version.

Now, to my idea. As you can see, the failed version/concept art has a large transparent background. That's because this was supposed to be on layer 7. Layer 8 will contain (nope! Not a textured background, god I would hate that in) a bunch of pixel clouds set on a blue background, with an auto X/Y speed. Clouds moving. If you get my drift.

Problem is that I'm just a very shitty artist. So I'm asking if anyone can try it out?

EDIT: Lazily put together example of what I have in mind:
