As I mentioned in the description for my version of Jack, this is his twin sister Jill, which is indeed an original creation of mine even if it's very possible that others have done this that I am not aware of.
Thanks for enjoying my concepts once again guys. I know that I'm going to have fun with the bad girls club that she belongs to in future stores with them. As for Jack and Jill doing different things for Winter, there's no reason that they couldn't, and I agree with you to a point, B. I just don't want to limit one or the other as to what they can do such as Jill can only make it snow and Jack can only freeze water, I'd rather them be somewhat interchangeable but divide up things like the above between them.
Cool distaff counterpart. Some differentiation between Jack and Jill's specific domains might be interesting, btw... like they're responsible for slightly different aspects of winter. If the folkloric Jack Frost had a sister, they'd probably serve slightly different purposes. Not that what you've done isn't perfectly fine as is -- just food for thought.
