Taken at the Out of the Darkness suicide prevention walk in Chicago yesterday with a 6s plus, no edits. I have to admit... I don't love it.

Taken with the front of the 6s plus at the walk. Apologies for my appearance. Was a hard day.

I don't know. I almost feel like my 6 plus was better. My 5s was better. I'm not sure what I dislike so much, but I haven't really been happy with any images. The first picture I took was using the front camera and it was so bad I'm not even going to post it. Looks like a joke. :/
Might I suggest:

I think some education may help??? That is a neat website, however I'm not saying you don't know what you are doing, all of us could learn new things...
Your selfie is bad because the sun is behind you and it is putting a lot of glare on the lens. Have someone shield the sun (hold a hand up to put a shadow on the front of the iPhone) and it will look much better, or simply turn around.
