I wouldn't think that's copying. Like the other's said, I see it more as an inspiration. As long as there's no completely making it an exact replica, I doubt it's copying. There are tons of ways to make characters, despite being slightly limited to what FH has. This is why I adore making presets. You can make your character any which way you want and make them more unique to your character. It only sucks that we're limited to 12... -pouts-
So no, I don't think this is copying. At least on a full blown scale. It's inspiration. And if the person you got that inspiration from politely asks you to change, don't argue, just do it. This will save a LOT of drama in the future.
