Once you've established that your previously naked characters wear clothes now, you shouldn't renude them and have them locking their arms together for the DVD box. This is just a few steps and/or a more generous cropping away from DeviantArt material.
Although I like Chip and Dale, even I found this to be disturbing. There's just too much of their bodies showing.
But I did suspect it to be a fake since Dale's coloring is off and the character design isn't the same as in the show (it's from an earlier era). Sure enough,
here's Amazon's version. It's either the real cover or a redesigned one. Unfortunately, I think it looks even worse due to the heavy shading. But at least Dale's no problem to look at.
Personally I think there are a few other sites of horror art more deserving of "a few steps away from that material" than DeviantArt. I've seen stuff on dA that convinces me their guidelines don't mean jack, but overall their stuff seems decent. I guess it really depends what you search for.
