Subtle. I love the eyes as they stand out with loads of expression. I have a black cat and photographing her is a challenge because blacks run close together. In real life it's no problem seeing shapes, but in a camera, it's hard to get all the dimension we see and know to be there. That's probably why I can see all the information you put in like the nose and planes and all that -- It's like home. So nothing needs to change whatsoever. It's perfect.
