I think you did not pick the right mocks to show your logo. The task is about creating an icon/logo for a browser extension, which will most likely be displayed in the extension store and as the extension's icon.

However, you chose to display your design on the FPL website and a mobile device. Although both may show the variations of the logo, it will not be used in that way. Tagging @amosbastian so that he can leave his comment here or get in touch with you on Discord.
