I like the expression on the llama's face. However, I think the whites show very grey in this photo. You might consider shooting the llama without the tree, as there is a lot "going on" in this photo and subject gets a bit lost.
Funny subject that has some appeal. I don't like that the llama is centered and think you could have cropped from the right without losing anything of interest in the image. I'd also like it better if the whites were a little stronger...the light just seems flat to me. Focus needs to be sharp around the llama's eyes at minimum.
