Create a humorous image illustrating the adage 'the quick brown fox jumps over the lazy dog,' using CGI and traditional hand-painted techniques. The fox should have a mischievous expression and be covered in dirt, while the dog appears sleepy and unimpressed. Model the animals meticulously using 3D software like ZBrush. Use Unreal Engine to set up the scene with realistic lighting. For the hand-painted elements, employ proprotion sketching techniques in Autodesk Maya.
