In modern usage, ame-onna is a girl whose presence seems to bring rain, especially to important events. For Urami, it seems to be doubly unlucky, as most of her unfortunate circumstances have happened in direct correlation to the rain.
I also love the way you showed where raindrops had hit her shirt in the first version. asjdlfkajsldf I'm such a big fan of rain. I think it's so magical. I'm glad you did both versions because I've learned a lot from watching, as well! ^^
