Someone holding a frisbee in front of a tall tower with trees

I want a class emblem that represents our class。The theme is unity and growth，It symbolizes the team spirit of our class and the goal of mutual progress。 The class emblem should be round，The diameter is about 10 cm。The main color is dark blue，Symbolizes stability and professionalism。There should be a pattern in the center of the class emblem，It can be a tree or a symbol of growth and hope。This pattern should have a simple and modern style。 Around the tree，I want text with class names。The name of the class is 'Blue Sky Class'，Use white fonts，The font style should be legible。 Make sure that both the tree pattern and the class name are centered on the class emblem，And clearly visible。if possible，Add a small flag at the bottom of the tree，It says '2023'，to indicate our graduation year。
