Wish I had the pencils or inks for this one handy. But in short Valerie did a bang-up job making it what it is. The reflection from the puddles is particularly striking.
People have speculated that Hanna's departure could go either way, with her going home or going back inside. I disagree haha - the latter is too depressing! The umbrella is a guiding light in a world where she is alone, truly alone, her body's sole inhabitant. I saw some hope - is it hope? - in embracing that. Maybe not hope. As the series was coming to a close, it was heavy on my mind that no amount of acceptance, awareness, or permission has any bearing on the inevitable end. It's a cope, as we say in 2020. But implicit in coping is an acknowledgment of the truth, which is what Hanna is stepping into. That is optimistic, to me.
