<https://s.mj.run/TwbA1mTeCgc> Design a hand-drawn style icon representing 'Masterclasses.' The icon should feature a prominent canvas or picture frame in the center, with a crown placed elegantly on top of the frame to symbolize mastery and excellence. Surround the canvas with multiple small cameras, representing the documentation and sharing of knowledge through these classes. Use green (#94e28f) as the dominant color for the icon, and keep the overall layout balanced and clean, with the cameras subtly encircling the crowned canvas to highlight the theme of expert-led learning.
