Nemo and his friends have found the perfect spot next to a drain, letting them easily access the flowing water. They are grasping the edge, smiling and looking around. To colour this picture, one could use blues and yellows to draw out the liquid element of the image, while also incorporating vibrant oranges, greens and reds to highlight the joy in Nemo and his beloved friends. For example, one could give the drain an orange and blue funky pattern and make Nemo's fins sparkly blue. Meanwhile, the other characters could be brought to life with a mix of lively greens and reds. A deeper yellow in the background may bring the sunniness to life, making the overall picture a stylized and captivating work of art.
