Who is in a profile picture?

I love your analysis of the data. It is simple, succinct, and clearly portrayed by the data chart you presented. However, I would be great if you had some form of documentation besides just written words of your project. Perhaps a screenshot of the sorted pictures? I also like the questions that you posted at the end, but perhaps you could try to answer them yourself using the project? Though, the data chart is a little confusing to look at. What parameters are you using to create the averages?

I find it interesting how you came to the conclusion that having more people in your profile picture may be an indicator of your desire to flaunt your social nature. In my own project, I found that having more people in your profile picture is actually an uncommon practice, as doing so deflects the attention away from yourself,, and towards people that your audience may not necessarily know. In most cases, this is an undesirable effect. I think it's important, in your case, to analyze who exactly is in the profile picture in addition to the main individual, and how that portrays the individual.
