Hm, curious. Contrary to you, I don't feel anything when looking at that picture. To me, the person depicted has no connection to Asuka. Yes, she looks like her, but that's it. The Asuka we see in Eva would not behave like shown in the image. For me, it's just another picture in a long list of pictures *not* showing Asuka, if that makes sense. Looks like some edgy fashion shoot for HotTopic or something. Just describing my reaction here, not arguing against what you said.
@Berserker: There's a translation of the doujin you posted (and a second one by the same author). I'll uploaded it to IMGUR for people who don't want to visit Hentai sites or search for it on some other obscure website. I just love their expressions. Time to practice my own drawing skills ... sigh ...
