beautiful image. we should all be so lucky to witness something like this. wonderful composition and coloring. one of my top picks for the challenge. hope it does well for you.
Great sky, and good idea for the silhouette, but, something about the giraffe looks a bit off. It looks too smooth, so I am guessing (and I apologize if I am wrong) that this was post processed a bit too much.
An interesting image. The sunset colors are good and I like the graduation of tones. The placement of the horizon is good too, as is the placement of the giraffe in the frame also. The tree does a good job of balancing the image. I keep looking at the legs because they look so weird. It looks like one leg with a hole in the middle. It's interesting how the mind fills in the blanks. It's nicely sharp, although a tad oversharpened with the white halo standing out more against the black silhouette.
