Hello there! ^^
I wanted to explain how dA works, because it seems you don't really know how it works.
What you have created here, this account
BriAndFriends is a personnal account, on which you are the only one who can post. And on this personnal account, you are supposed to submit your own art, and not art that doesn't belong to you.
Submitting art that doesn't belong to you is concidered theft and can be reported to the admins, which could result into a banishment.
So to avoid this, you should delete all of the stolen art before you get reported.
However, if you are willing to create a group, I think you can find some help here;
FAQ #418: What are Groups and how do I make one?Hope it could help!
