Prevent any imperfections or unrealistic elements in the image of the girl painting on a canvas in the art studio. Ensure that her facial features are realistic and well-proportioned, with no unusual deformities or distortions. The lighting should be natural and soft, with no harsh shadows or unnatural lighting effects. Additionally, the girl's posture and the way she holds the paintbrush should be anatomically accurate and artistically convincing. The colors on her palette and canvas must adhere to the typical range of artistic hues. The image must be entirely realistic and true to life in all physical aspects
