Yellow is challenging and you are succeeding! Nice saturation of yellow here. You can try using ochres for toning – looks like maybe you have. And use yellow’s complimentary color of purple very lightly for some shading and darker areas. Also the earth green can be good for shading/grisaille sometimes. Do some practice tone bars. 🙂
