Good full frame but possibly too shallow a depth of field. The eyes seem to be the focal point but because the cat's head isnt straight-on the right eye is a little out of focus and so a little unbalancing to look at. Good lighting and color although I think the catchlight in the right eye is a little distracting due to the position.
Very nicely composed shot of a great subject. I think you would really highlight those eyes if you darkened the shot a bit and maybe sharpened it as well. But still, this is an excellent shot as is.
