Thank you to all the replise, I had some thinking to do...
I decided that after all, I too prefer the tail placement of A/B, so I stuck with that design. I did try to change the base of the tail a little, and added an idea of shading (though I'd leave the actual shading to my artist, I really loved how he did my tattoo so I'm not worried. I still can't decide between the eyes open or closed - closed it seems more serene, but open is more intense. I tried doing them both in color and keeping the black and white, and I though I was thinking of a B/W only tattoo, I seem to prefer the colored version.

actually, I dug up from my external hard disk the pic that I keep remembering when I think of this cat, and I more and more warming to the idea of the open eyes

you can't see it well, but he had blue eyes, some days looking more greenish... sigh how much I miss this cat...
