I want to say thank you for making this this is for want of a better term gorgeous. "Protect me" is an appropriate title. It seems there is a beautiful and elegantly mutual protection of the girl and candle to each other. The candle as almost an extention of herself shines a light and obvious display as she hold it stably on top of her hand.
It like how your sister has the multiple role of providing the focus of the picture; although being more the holding part and the background of the picture. You made a good choice but blacking out everything behind her and blurring her core outline. Withing the span her arm the focus moves from crystal clear to unrecognisably blurry.
Even the length and the proportions of the candle seem thoroughly and beyond appropriate.
You have made the mood of the picture asthetically vauge enough that you do not know wether she is holding the candle up or the candle is holding her up. There may be some position issues with this picture but this is near perfection. This is a beyond well deserved picture and all the more deserving of the term masterpeice.
