I put down base colours on the eagle. It is very rough and just putting the basic colours down to have a rough idea where the light and darks are.
I then took a blender to it all to smooth the colours out. I did try to follow the shape of any feathers I will be drawing later, but at this stage it not that important that everything is in the right spot.
Finished blending the base colours and now to add the feather details. Like with most types of painting, it does help to have a basic tone down first to help with future shading. I do find its harder to work with a completely white canvas, whether that is a digital canvas or a fabric one.
