I've never heard of Rilke, but the first thing that came to my mind when I saw this was Edgar Allen Poe. That's a compliment, for the record. Images seldom spark such a specific reaction like that, well done composition!
woww. this artwork is very.. powerful I guess I could say. I was very drawn to it from the first moment I saw it. and I also happen to be a little familiar with Rilke's poetry and quotes. this is just incredible <3
