Way to take a good profile picture?

[Kristen Masencup]

I always see these girls on facebook and they take these amazing photos of them with like half thier face, lit perfectly, actually looking at the camera instead of taking these ones with the phone actually being seen in the mirror and get so many likes and mine are all fuzzy and dim with the phone in them. How do I take really good pictures that look like all these other girls that have pictures that look so pretty and get so many likes?
Also I would like to know a good editing site where I can put my pictures on and edit them to make them look good.
