I'm kind of joking about ugly (and completely serious about the names[1]), but using real photos in your mockup will give you a much better idea of how it will look in the real world. Sometimes the lack of consistent polish will make the whole thing fall apart, so something that looks great with high-quality stock photos will look terribly with everyday average photos. I'd bet that would be the case here, with the focus on "clean" design. Of course if you're making a website for models or photographers, then ignore that completely. The take-away here is to know your audience, and design accordingly. Facebook should be (and currently is) optimized for getting a quick pulse on what's happening in your social circles, and the designs presented here are a poor way to accomplish that. [1] Long names cause weird word-wrapping and overflow issues in many designs. India seems to have a high density of (by my standards) unusually-long names, so if you expect to have a lot of Indian users that kind of thing is really important to consider.
