Nice pets.
The cat is a bit dark, that is the one that would need some brightening. But I also find this crop too close. At least the eyes should have been open at the time. A pity that they aren't ... and I mostly feel that the triangle ears of a cat are essential to a cat portrait. (My opinion).
Focus on your little dog is not perfect, I feel it needs to be on the eyes in close-ups like this, not on the nose. Though I do see you went for his licking his nose and for the pink tongue. But I really long to see the eyes in focus, too, so maybe a smaller aperture could have helped.
Thank you for your opinions. Yeah, I think I would've liked picture #2 better if I had focused in on her eyes. In #1, I had a lot of junk in the background, so I cropped into his face a lot more. Thanks for the comments!
