A Tattoo Design. He wanted a lot of elements on there. It was to cover his whole leg if I remember correctly.
Perhaps the kid sitting atop the tall island is imagining all the strange details around him and the carnage taking place below the water. Or maybe he is unaware of it all. But why should we assume he is even the protagonist? Maybe the sun is, or one of those crows. However, the kid is a human and so is more relatable to whoever is viewing the image. A crow wouldn’t even know how to use the internet and even if it could it wouldn’t know what it was looking at. Dumb crows. There are two other humans in the illustration, but I don’t think anybody would want to be in the position where they could relate to them.
