And just a note that I've heard from some girls is that for your pictures, some general tips is to be smiling in your pictures. If you look happy, you may appear more confident. Also, don't take pictures from too high or too low of an angle. Too low means you're looking down at the camera and you may look a bit intimidating. Too high and you look like you're posing like some insta-model.
Also try to have one or two group photos so you don't look like a loner (though personally speaking I like never take group photos with all my friends lmao).
