It depends just how basic. You can't copyright an idea, only the implementation of an idea. But if the implementation is similar, it might be seen as a copy.
With a basic geometric shape like a star, it'd need to be practically the same to be an issue. Even then, it might not be (a plain star is a plain star is a plain star - pretty hard to claim originality on that).
Specifically with what you've described... I wouldn't be worrying.
