Tom the grey cat is in hot pursuit of his arch-enemy, the brown mouse Jerry. They are both running along the rough brick wall, with Tom in the lead, trying to catch up to Jerry. To give the image more depth, the brick wall could be painted in lighter and darker shades of brown and grey for more texture. The mouse and cat could be coloured with a more cartoonish palate, with the brown of Jerry's fur slightly lighter than the wall and Tom's grey fur slightly darker. The eyes of both Jerry and Tom could be detailed with green and yellow to give them character, and their feet could be coloured a lighter colour than their fur. The chase could be highlighted by adding a streak of orange behind each of them to show their direction and speed.
