Spectacular portrait of an angry leopard, skillfully recreated from the reference photo, but not, however, as a sheer copy.
The first impression is left by the authenticity of the painting. The detail is very clear and very well defined resulting in a realistic look, although the author has also managed to preserve the artistry of the media. Some important details, like the fangs and the eyes, are "brought into light" which contributes to the animal's character. Technically speaking, there are a few remarks I'd like to make. The composition is fairly simple as nothing more is needed. It doesn't ask for so much space on top, but this is a minor issue. The colors are well picked, the hue variations are skillfully used to outline the face's mimics and fine relief. I find the red hues are a bit too exaggerated and this takes away from the natural look. However, this color in particular corresponds very well with the expressed emotion and I assume it was deliberately chosen. A bigger problem for me is the background. The simple dark tone really makes the leopard stand out, but this black is too neutral for this picture and stands very harshly against the leopard's face. Such pure colors are best to be avoided.
Finally, I'd like to say this painting actually looks like more than the original photo. The author tried to inspire certain feelings into her work and she positively succeeded. Especially captivating is the look in the leopard's eyes, which somehow truly instill her emotions.
