Create a low-poly picture of Athena's owl. The owl wears shiny armor and a big helmet. It holds a strong spear. The owl sits on a big, green olive tree. The tree has soft, pastel leaves that go up to the sky. Use simple shapes and bright colors like light blue, pink, and yellow. The background is clean and simple. The owl and tree are the main focus. Make the image fun, modern, and easy to look at.
