It's so easy working with models that co-operate with you.
I can't see any detail, maybe that is the look you were going for, but for me I can't see the eyes.

the Dog is under exposed, you need much stronger lighting or use flash

I like #2...Maybe you could brighter her eyes in ps?

Much of the details in the black are lost. Did you do any PP work on these?

They all have a colour-cast (at least on my screen), especially #2 and 4. There's a lot of noise in #4 - too much PP. I don't like part of the dof cut off in #3. However, you've done the essential thing - taken from the dog's level.
BTW, I love Gracie - she's looks like my type of dog.

The only one that kinda works for me (from a PP point) is the last one. It looks like an authentic aged photo, great job. I wag my finger at number two. You could have done better, at least brought the eyes out just a tad.
