For a stock image I think I'd boost the contrast and color saturation a bit -- you want your image to jump off the page and attract the attention of the purchaser.
Awww. . . really cute! At our zoo, it's hard to get close-ups of the giraffes because their area is so huge, and they always stand way in the back. So I really appreciate this close-up. Good luck.
I like the composition. The image appears a bit soft, should see more detail in the fur. Being an advanced editing challenge you may have tried selecting the giraffe, inverting, then blurring the background some more.
