Sure you want to be sharing a person's real info on a public forum? Some people might not appreciate that.

: Someone has taken a low resolution version of my Halo design, edited it, and
: is now attempting to sell it on Amazon as his/her own art! Tge idiot thief
: remives Cortana's details but left my signature intact!

Kind of odd that they'd *remove the details on Cortana but leave the signature intact. It's wrong either way, but it's really weird. Wonder why...

: That's Not All! EVERY DESIGN under the account is stolen. Many of which are
: from fellow artists over on the Ript Appeal page.

Now I can't help but hear it like a sales pitch... But yeah, Amazon has a way to deal with copyright infringement. I'd shoot them a message or two.

: I plead to you all to help put this account down. Give bad reviews for stolen
: art. Thank You.

Won't give a review for something I didn't buy, but yeah, looks like you got a real case on your hands. Then again, you did make this using likenesses and assets from two separate copyrights, so there's a touch of irony there. Either way, best of luck!
