You can change all of the skin elements - that is not made originally by you, if you want to share your skin here.
Normally if you leave it be, nothing else happened. Only to give you a brief about the do's and don'ts in the skinning subforum. However if you want it to be deleted/locked, feel free to contact Global Moderation Team members (GMT). You can chat with
RockRoller here.
Next time before sharing your next skin, try share your "original" skin.
Mixed skin can be shared through your
userpage or
signature below.
