I prefer it to the actual full-sized poster because of that sense of endlessness given to you by not even being able to see the top of the tree. I also thought the dragon in the full image was out of place in the benign yet intimidating tone of the thing. The half-image you have in the map is perfect, as it pushes the character a bit more into the corner, and centers on the tree and the herons. I need to find a way to make that a wall decoration.
