Mascara Answers

In a couple of days I’m going to have to do my own make up, besides eyeshadow & blush, for my school’s musical. I’m not sure what to do though. I have eyeliner, mascara, powder, & lipgloss. I’m pretty pale, so the lights are going to probably wash me out a bit. Should I use a good amount of mascara & eyeliner to make my eyes “pop” a bit more? What about lip color? Should it be harsh? And advice is very welcome[I can't really ask anyone else I know in real life...]!
