Create a minimalist cartoon art t-shirt design featuring a single iconic character depicted in a humorous situation, appealing to adult sensibilities. The character (e.g., Snoopy, Garfield, or Charlie Brown) should be illustrated in line art with strong outlines, showcasing a funny expression (e.g., lounging on a couch with a remote or holding a coffee cup with an exasperated look). Use minimal color, incorporating one or two accent colors for humorous elements while keeping the majority of the design in black and white. The text "Just Another Day" should be integrated into the design in a clean, sans-serif font, placed either above or below the character to maintain balance and simplicity. The final artwork should be prepared in a high-resolution format with a transparent background, ensuring it is suitable for printing while emphasizing the simplicity and clarity of the design.
