Hi, it looks to clean because the subject just lacks value, adding some shadows and highlights can make it more 3d, I really recommend studying the planes of the head since its a really helpful tool for shading and structures of the face when studying portraits you can also try changing the painting to black and white and check if the character pops out more in the background and more visible. I also recommend understanding your light source when it comes to shading. | Artwod Feedback
