I've been working on my portrait of the little girl and her Beagle. I started with the Beagle's face. I've taped the original photo composite to a blank spot on the canvas for reference. Here's the underpainting:

I used blending medium to keep the underpainting from drying, and began mixing in the main colors.

I added the eyes and nose and put in more detail on the fur.

When I had the dog at an intermediate point, I began work on the girl by laying in the pinks in her skin.

I then covered the pink underpainting with a mixture of Titan Buff and some pinks and browns.

I added the colors around her eyes and mouth before painting them in:

Once I added the eyes, the portrait began to look more lifelike.

I then added her dress and hair, using pink hues throughout to tie it together:

Here's a closeup of their faces:

Next, I'm going to work on adding the rest of their bodies and the background.
