Alien abduction piece on Deviant-art?

You may not have been the only one to notice, which could explain why you can't find it anymore. If you don't know the name of the artist and don't have the link anymore, there isn't a whole lot you can do to find it on an enormous site like DA. DeviantArt users are very good about reporting that kind of thing so you can at least take solace that if it hasn't been caught already, it will be very soon.
