Create a photorealistic square image (1080x1080) showing a custom acrylic keychain version of the [LOGO] logo hanging from the zipper of a dark-colored backpack (e.g. black or grey). The logo must retain its original shape, color, and proportions without any alteration. The keychain should have a clear glossy acrylic layer, clipped with a silver metal ring and clasp. Use soft daylight or diffused lighting to avoid yellow tones. Set the background in a modern outdoor setting, but keep it blurred to maintain focus on the logo keychain.
