Once the base coat is dried, I liberally applied thinned dark blue ink over the entire model. Â I don’t always use inks and washes but it works well with tiny scales to easily shadow around every one of them.
The ink will take a while to dry. Once it’s ready, I go over every scale individually with a mixture of the base color and a lighter color. White lightens blue nicely.  I use thin paints and go over the model several times mixing more highlight in with the base coat.  The last highlights are sometimes pure white.  This depends on the size of the details and where they are positioned on the model.  The claws, teeth, and spikes I brought up to white.  The  larger belly scales and some of the details on the face got another wash of black and blue mixed together to create deeper shadows.
