There is that pleasureable feeling you get when you watch rain fall through your window with a nice cup of hot drink in your hands. You are comfortable and dry, enjoying the nice cool weather.
This drawing portrays reality as the girl stares out watching raindrops. I do wonder what is going on through her mind. Could she be missing someone or thinking of her future? Perhaps she is longing to go play in the rain like we did as children.
A lot of ideas are running through my mind, maybe i would write a story based on your drawing. I hope you won't mind.
