I'm not certain beauty or how we judge it are absolutes. There are cultural and societal influences, there's our own understanding and learning, there's personal tastes, there are reference points.
When you ask me whether I find androgyny visually attractive, short answer is I don't. Then again, I don't find it unattractive either. It's just as a label. If you ask me whether I find a specific person attractive or not in his/her androgyny, I might respond yes or no, depending on what I think I'm looking at, and in what context I see it. To take it away from the context of people, I like interior design and there have been homes I have absolutely drooled over, but that I know I wouldn't want to spend an hour in as a guest, let alone live in. Same in the case of people.
I don't find this kid particularly attractive, but it could just be that I don't like this standard modeling pic of someone glaring at me (why? what did I ever do to them?) or fat lips. I also don't find him sexually attractive, because, to me at least, he barely looks legal, whether as a boy or a girl, and because my first crush was on Tom Selleck and that tends to my "type" if it's confined to the merely visual.
David Bowie in some of his disguises though, even though he looks nothing like Tom Selleck? Oh, yes please!
