Thirteen's a good place to start!
I would add - take a good look at the card again. Is there anything that strikes you about it - in her posture, the flower, her cat, the lions above her head or on the side of her seat, the colours? Is she looking at something - another card in the spread, for instance?
Then maybe, stop thinking, and try and feel. What does this scene, this character, make you feel (happy, sad, energised, cross?)
You bring all this together. Try journalling. I often find, when I'm stuck on what a card might actually mean to me right now, when I journal eventually I have a breakthrough. I start with all the "known" meanings, with my observations of the card, my feelings, then keep going (sometimes several pages) until eventually something opens and I break through.
(that's the advantage of reading for yourself - when you reach the inveitable blank spot you can journal about it. When you read for others you have to hope breakthrough happens during the conversation...)
