This article seemed to be a hit...(2 samples are below) 22 Pieces of graphic design that was ripped off Disney uses their own inspiration. Hah.
Not all of them but most. As far as Disney, they used pic templates that were in essence drawn over. So alot of poses and animations are either true duplicate or mirrored versions. When your making animations you have to sometimes make a shortcut and considering, the racist, that is Disney was a forerunner in animations. Its a 'normal' thing. I guess when you create your own style, doing what you want to with it is a perk. Alot of anime is the same way.
Definitely not all rip offs. In fact, probably all of the album covers could be considered parodies, since a lot of them seen to be some rapper using the obvious iconic styling of a vintage cover. On another note, your should probably remove the ads from your portfolio page.
