I just went and had a look at your gallery. If there were a word for your skins stye, it would be, "uninspired". Perhaps when you get an idea for a skin, you should search the site to see if it has been done before. If so, you should make sure that your version is different than previous ones, or, maybe consider making something else that has not been done before.

As of yet, no... I don't leave any room for my skins to be mistaken for another. I dislike being uncreative. xD; There's a lot of good Link skins out there, maybe you should try making something unique so that it won't be mistaken.
