Not only is this a gorgeous looking cat, it's also a gorgeously taken photograph.
What I really like about this shot is how the overall tone perfectly complements the colour of the cat's smoky fur. While the composition isn't an unusual one, I don't think it really matters that much because the combination of the tone, lovely focus and those piercing orange eyes packs enough of an impact as it is. Also, the choice of a square crop really works well for this type of image.
All in all, I think it's a wonderful photo that captures the beauty of the subject perfectly.
