If you can't pluck your eye brows due to uncontrollable circumstances, at least trim them shorter. A slightly thinned eyebrow is better than nothing. Try spreading it out over a couple weeks. The same does not apply to your significant other however. Make-up is harmony between shadow and light, that fashion the different areas of your face.
Shadow hides an area while light gives it prominence.
You want to highlight you best features. Makeup can not create something that is not there. For most, over the moustache and chin area will be good enough. Others with heavier beards will need to cover most of their face and neck. If it looks like you over did it in a tanning bed, then you got it perfect.
