One of these days I took more than a hundred pictures and after reviewing them, there wasn't any that pleased me. Not a one!!! I was very bummed out after that, but, that's life! So, my advice to you is don't get discouraged, go out and try again!
As for pictures, well-lit locations tend to produce better results. Avoid flashes. One other thing: consider getting a tripod. Also, having a camera with a timer function helps immensely.
As for make-up, since I haven't seen the pics you are referring to, I can't give specific feedback. Well, remember that practice makes perfect!
Good luck!
