This is really cool art! I haven't read "Cat's Cradle" yet, but it sounds like an interesting title and story. I've heard of Kurt Vonnegut, though! He was a very creative writer.
This is my first time learning about Ena as a character, and wow! It's really interesting that she's a humanoid, and she has a lot of unique traits as a character. It seems her emotions play a big part in how she relates to the world around her.
