This is absolutely beautiful, and thus very hard to critique. All I can think to say is the grass is kind of blurry and blendy-into-the-horizon-y. But really, wow. It's wonderful.
Nice! Makes me feel like I'm on an African safari. The silhouette of the giraffe's long neck is not one we see often. Could be on the cover of National Geographic. I wonder if you deepened the tones of the sky color if it would ruin it? Hmmm - just thinking out loud. Nice!! 8
