The Bratz - Bartz are in the middle of their studies, or making a plan for something, at a desk. One of them has her arms crossed and a determined look on her face. The other one is gripping a pen and looks focused, as though they are both hard at work on something important. They both have open notebooks in front of them and a few scattered pieces of paper.
To color it, use bright, vibrant colors to bring the image to life. For example, paint the desk a vibrant yellow, the notebooks a deep blue, and the paper a bright pink. Use pinks and reds on the Bratz-Bartz to bring out their natural beauty, and give their eyes a bright, sparkling gleam. For the details of the page, use metallic colors to really draw your eye in. Finally, use blues and greens as highlights to give the image a bit of a dynamic, energetic feel.
