I'm into the grain in this - very well composed and a nice, unique take on the challenge. I like how the hat kinda doubles as a "sun" for the tropical motif.
So ya look like the underside of a hat? lol I ran out of time while commenting during the challenge. I thought this was a tropical-fun kind of picture. And like the others said, I like the touch of noise as well.
that is a fascinating hat, but the angle you took of yourself is simply not working. From above or the side would likely have been better. Also not keen on the noise.
I like the perspective of this picture but since the topic of this challenge is self-portrait I would have like to have seen more of you in it. The hat over powers this picture and becomes the main topic of the picture.
Interesting. Different point of view. Although I like those photos, I think you should of show a bit more of your face. As a "photography" piece, it's very nice, cool... but for the challenge, I think more face would do better.
