POSSIBLE CLEARER IMAGE!!!
http://www.serebii.net/index2.shtml
There is yet a newer post today. Overnight, a new image cropped up on Japanese Image Boards that is supposed to show a clearer image of Shaymins sky form. However, since the image doesn't have a traceable source, it is likely that it is fake. Nevertheless, it is there, and it could be real. Bulbapedia doesn't have any information regarding this picture, just to let you know.
I would post this picture on this post like Coach did above, but since I'm relatively new to the forums, and Serebii won't let you copy the picture, I have no way of doing this. Even if I could copy it, I don't know how to post it. At all. Sorry.
Couldn't think of anything better to put here, so... yeah...
