If you have discoloration around your eyes, I would apply foundation or concealer to even it up.
Are you using decent quality shadows? When I first began wearing makeup, I would pick colors that had crappy pigmentation and were too pastel.
I bet some dark shimmery bronzes would be stunning on you, but they wouldn't be too extreme. Your picture, unless the flash is washing you out a little, doesn't make it look like you shouldn't be able to wear browns, either. Maybe some plums would be good.
