Create a logo for a masterclass dedicated to Omar Bongo Ondimba, former President of Gabon, focusing on themes of peace, science, culture, and the environment. The logo should include a stylized portrait of Bongo Ondimba at the center, surrounded by symbols of peace (such as a dove and an olive branch), science (atoms, globes), culture (traditional Gabonese patterns, musical instruments), and the environment (trees, leaves, animals from Gabon's wildlife). Use a color palette including green, blue, yellow, and white. The design should be modern and clean, with rounded shapes and an elegant font for the text "Masterclass Omar Bongo Ondimba" at the bottom of the logo. --s 50
