Michaelle: I'll try more of a panoramic layout on this, yours is a valid suggestion. It'll also help to make the bird in the center of the image stand out a bit more. On the other hand, the fact that the moon is overexposed will be more apparent ...
The colors in this are outstanding, I love the deep purple tones... however, the large dark foreground does not add to the image, and competes with the beautiful purple. I hate to say it, but maybe crop out some of the sides and the bottom to balance the image just a tad bit more.
