Design a digital art piece featuring a whimsical scene of gnomes indulging in potato chips in a fantastical forest setting. Consider the gnomes' facial expressions, posture, and clothing to convey their delight in snacking. Incorporate vibrant, pastel colors and subtle textures to create a dreamy atmosphere. The art piece should be visually appealing and evoke a sense of wonder. Please provide a detailed description of the art piece, including the characters, environment, and any symbolic elements.
