Dark Sky Vulture

I had several images of vultures soaring, basically because they glide around in circles at a leisurely pace so I can often predict where they'll be. This image had a grainy-looking sky so I played around with it in Photoshop, inverting the color and so on.  The circle was created using a lighting effect called lens flare.

I considered cropping this so that it would look like some sort of flag but I decided to place the bird a third of the way across instead. Hope you like it.
