Dude, not cool to hide comments telling you to fix your gallery. We're only trying to help, but now you're clearly proving that you know you're in the wrong.
You do not have permission by those artists nor companies to post these works as your own. You're in direct violation of the Deviantart terms of agreement that you yourself agreed to when joining the site.
Save yourself the trouble, ok? Just take those pictures down and start posting artwork that you yourself have created. That what this site is for.
