definately between #3 and number 4 it helps your cheekbown lines and your facial expressions in 1 and 2 definately say no.
You readjusted your hair in #3 and then you looked at the camera with your chin slighly down on #4 and your hair was a little out of place again. I think you had a tough decision between #3 and #4 and only because #4 looks like you looked at it after the others and later because out of place hair on the right side... And it appears your pursing your lips tighter in the last picture is what a person does when they are taking a serious picture, which youy would do with the pair you chose ....
I'm going with #4...
Now I play poker and can read tells but I need alot more info then these photos, but I am sure you did not pick #1 or #2....
If you picked #1 or #2 we need to teach you poker you'd kick butt!
