OMFG Never did I think in this lifetime that my art would be even good enough to be stolen. OTL

The person ~xXscourgefanficXx claimed that my fanart of Shugo Chara is hers.

This is my entry: [link]

And this is her entry: [link]

And now that I'm in this situation...I have no idea what to do about it!

Should I report the person? Should I warn the person instead? Or should I do nothing?!

I'm so stupid. I received two notifications from two lovely people warning about this person who stole my artwork. It's not my characters...so it's not a big deal but I do find her criticism on my work a bit annoying when she didn't draw it I know I'm a crappy artist.

Anyway, I was hoping if anyone can help me with this problem!

If I do report it, can someone teach me how the hell do you report a person?! *SHOT*

[EDIT]: Someone has warned the user and she has deleted the submission from her gallery~ ALL GOOD NOW. :'D It's so good it was fixed early.
