The things I can see when I add symmetry. A large green nose? Frowning eyes? A butterfly, a cats face? Two faces in profile looking downwards. There’s probably more that you can see too. Human eyes are always looking for patterns, shapes, looking out for monsters or problems. I guess it depends where you place the connection between the two sides. You can get more or less pattern by changing the centre line. I think there is also a 3d feeling because of where the hedge in the center is positioned.
