Hetare

The robots name is Hetare (pronounced, He-Tare), his name is inspired by a birds name in a Manga i've read, i completely butchered the name when i would read it in my head, but i liked the name so much i went with it, the Cats name is Morgan.
I'm using a new canvas size, its the default poster preset for photoshop, let me know what you think? and is this preset ratio good for A3 prints?
