Gru is beaming with joy as he proudly holds a lush, healthy plant that has grown from his labors. Its tall, slim stem bears large yellow flowers that add a bright and cheerful hue to the scene. To add to the joy of this moment, you can use vibrant shades of yellow and green to color the flowers and the plant, plus a muted brown for the pot. A pale orange can be used for Gru's face and simple blues and pinks to make him stand out in the landscape. He deserves a touch of sunshine to finish the look - make his cheeks and the tips of his shoes a bright yellow and his clothing a warm toasty orange. Let's make sure to make this an image of joy and hope.
