Custom Acrylic Keychain Product Mockup

Create a realistic square image (1080x1080 pixels) showcasing a custom [LOGO] logo acrylic keychain hanging from the zipper of a dark backpack (such as black or gray). The logo must retain its original shape, color, and proportions, with no alterations. The keychain should have a layer of translucent glossy acrylic, equipped with silver metal rings and buckles. Use soft daylight or diffuse light, avoiding yellow tones. The background is set in a modern outdoor environment, but the blur is needed to keep the focus on the logo keychain.
