My only concern is that some of your friends have commented on the pictures, and it kinda detracts from it. (example: second picture, comment at 9:30 am) What if someone were to say something negative?
Sure he is (though not intentionally, I'd bet). Although logged in, I could not comment on his photos, and I doubt he's connected with people on Facebook that are going to actively criticize him in the comments. So, they'll tend to be more positive than not.
