Flip the original Q image. Could be a picture of a reflection.
Either way consider both possibilities. The dark spot(s) or moles alone really make it hard to believe that the first twitter picture was that of our current POTUS 45.
The way I read it in terms of basic military strategy is it's smacktalking. In the first picture the head/face is not looking at the phone, the gaze is directed elsewhere. So the person in picture did not take the picture.
In the second picture, we do have someone who very much looks like current POTUS looking right at the phone/camera taking the picture.
Way I see it is that "Hey we can see you anytime, anywhere and I am looking at you right now. Say cheese!"
High level smacktalking and intimidation.
