You may not know the name, but if you have a Tumblr account you've seen 18-year-old New Yorker Sean O'Donnell. Sean describes himself as a photographer, model, actor, singer, but mostly he's a person, like Cameron Dallas, who has managed to gain a sizable following by putting pictures of himself on the internet. Nice work if you can get it.
If you look closely enough at Sean you can see that he's not truly a classic beauty, his nose is perhaps ever so slightly too large for his face, his chin slightly weak, his flawless skin perhaps a result of Photoshop, but is he attractive? Oh my, yes. With his big, blue eyes, and strong, athletic body, he could easily be an Abercrombie and Fitch model. And as a model, his most frequent photographer is himself, and he seems to have an innate ability to play up his own strengths. In his infrequent YouTube videos (he says that he'd rather leave video-making to those who "do it well") he also displays a poise, confidence, and a deep, sexy voice that will serve him well when he decides he wants to be something more than "Tumblr famous."
All of which is to say, I think he's rather nice, I like looking at his pictures, and I hope you will, too.
