I'd join the group that recommends you try to come up with your own creation. When it's something of your own you can become more attached to them as a character since you would have put in time and effort, less so when it's anything you copied from another source.

Not only that, but this character belongs to a friend of mine and she already had one or two instances just like this where someone blatantly takes her design and it always makes her very upset because she treasures her own concepts and, like a lot of people, spent weeks perfecting the look of particular characters long before the game officially dropped(a similar skin tone had her conflicted, haha).

But anyways, yes. While I can't really make you change your mind nor see the value that comes with being your own character's designer, I would ask that you at least try to consider the feelings of those of us who really love our own characters before blatantly taking off their work.
