I liked how the owl's expression seems like it's just gone through some rough times, and the trees also look very aged and a bit ragged, but still have much life in them despite their appearance.
I interpreted it as he's looking optimistically out across the land, but I agree about the life in his eyes! It's so cool how we can see two different vibes or emotions from the same owl.
It can be hard enough to read fellow humans' body language, let alone another species.
It's probably closer to some Terminator vision flowchart. Do I see something? If so, do I eat it, fight it, or have sex with it?
I do hope they have some happy times. Their lives seem very hard. Perhaps they get exhilarated from a good hunt or when they find a perfect roost with prime offensive views and good camo, or have twitchy little dreams like dogs/cats.
