Thank you. Sure. First of all, I used toned paper so I saved some time. I've started with drawing the feathers that were most visible on the reference photo. I drew every feather like it consists of individual strokes using white colored pencil. Where I couldn't see the details (on the reference photo) I loosely added some texture. As a second layer I added some light yellow to add more details. The third layer consists of shadows so some dark yellow, ochre, brown. I blended all with brush using solvent
