Power
No power. Sorry. You do have a creative job, so you have the power to apply hair and makeup as you envision it, but only insomuch as it aligns with the director's vision. You may see "Cecilia" as a raven-haired beauty, but if the big guy in charge sees her as a homely, strawberry-blonde mess, you'll have to discard your previous notions and appease the power that be. So no—that power that be…not be you. If you'll pardon the wording.
