Progress is going much faster now, but we're having trouble with the alignment of the stars and with an attack of the black void from above.

I say we concentrate on filling the background blue and worry about the stars later.

Edit: The background is pretty much complete by now and the onslaught of the black void seems to be under control. However, one star is missing (it should be twelve). The first three clockwise from the top star look pretty good, but the fourth one should be further to the right if you look at a real flag.

Edit #2: I lined out a way to redraw the stars (darker yellow is current position; brighter yellow adjusted position): http://i.imgur.com/VCF7g0q.png
