When we wear flats we stand on our toes to make our legs appear longer than they actually are in the pictures! Mirror pictures give you the advantage of being able to calculate which angle is best, and also of being able to adjust said angle. Detail shots are always fun, keep the observer interested, and moreover are easy as 1, 2, 3. Photobooth-picture fall under the category of selca, and like mirror pictures are a breeze to take while giving you the possibility to control what your face looks like since what you see is what you get. Photoshop is a godsend not only to magazines.
I personally know embarrassingly little about photoshopping so I don't use it at all if you were wondering but I do use the few photo processing tools in Picasa. Everything else is old blogger tricks, if you are planning on writing a style blog someday take notes.
