very cool! i like picture #3 the best. it's the most simple, it has a very prominent focal point, and it alludes to the shape of a star in a subtle way. great job!
Agree about #3 - simpler is usually better for this sort of image. A little more detail in the sky at the top would be nice, but a very good image in any case.
I like the concept.
My issue is with the sky, the clouds specifically. Just a grey backdrop makes it a bit, drab.
However, As mentioned, I like the concept and my personal Favourite is #1.
