My .02 would be that the first 2 shots are very uncomfortably posed photos with very forced expressions, "say cheese!"
And the third, the focus is on your elbow. So, I'm looking at your elbow.
These are minor things and obviously tough when you are doing "selfies" (as the kids say now).
Yeah I was using the wifi on my 6D for these so 'selfy'-ish. Also I did manual focus and noticed the focus was off on the last one.
