I did like your skin, and I certainly used it for inspiration! I'd be glad to give you credit! I don't see much use in deviating from things that are already good.

Honestly, when doing a character, there really isn't much I can do to change EVERYTHING, unless I want it to look like a complete inaccurate pile of crap.

When redoing the skin, however, there were aspects that I liked, such as your hair shape, so I used that as a guide. However, coat build, lack of cape, and boot positioning seemed very off to me, so I redid that.
As for the collar, it is a jabot, and it's sort of difficult to change that, though, I did add a bit to flow it out a bit more, in a similar way to the way I built Rachel Alucard's.

The skin color, and the lack of prominance in the face were also things I wanted to change.
I do not think the hands are something exclusive to you. You may look at my other skins to see what I mean!

I have plenty of fully-original skins, and anything that I do that others have already done, I often improve upon techniques to suit what I find is better to my tastes.

I apologize for using the skin, but I was more looking for something that had the predominance of the black already filled in, so I didn't have to fight with coloring all of that in the editor at 3am. If I make something, I do want deviation!

I can do one of two things for you.
1. Give you credit
2. Take this down

I don't mind either way! Let me know. I apologize if I upset you in any way!
