Wow, this is a very interesting image, the use of so many different images in this manipulation work very well together. The way it is arranged causes you to look deeper and deeper into the image. The detail of many objects and the scenery in the foreground looks very nice and combines well with what is going on in the sky, and everything is blended well. The only thing that I see that could improve on this image is the fact that you didn't really do much to manipulate the stock in the center of the image, that image is sort of just there as it was originally, I'd like to have seen some more details inside of that to make the image even more interesting than it already is.
