I'm now focusing on completing the paws. They have been very challenging. The paws are very dusty in the photo from which I'm painting and that doesn't work with the color of the dog's face. So, I've had to change several times the color of the paws and some of the values (lights and darks) to make it all work together.
I'm also dealing with the implied bone structure of the paws themselves, the implied strength of the paws and nails gripping the railing, and the subordinate relationship of the paws to the puppy's face. I haven't studied dog anatomy; so, I'm on a steep learning curve.
I've allowed myself the luxury of generous patience and enjoyment in learning all the subtleties of puppy-dog painting.
