Now for the final touches. We'll add some shadows and shading that will really make the details of the carving stand out. Mist the entire piece with water and make sure you painted everything you wanted to. While it is still damp, thin some black out a little and use the small brush to apply it to wrinkles on the face. Use the large brush with water only to blend it out. Use the same process on his muzzle under the nose. Darken it around the eyes, and up it the deepest parts of the ears. Do this in all the little cracks and crevices around the collar, the legs and feet, and around the tail. What you're trying to accomplish is similar to what people do when they antique a piece; you are trying to deepen the contrast, the shadows in the deeply carved areas. I feel like doing it this way gives me better control over what gets darkened, that wiping an antiquing solution over a piece and then trying to wipe it off. When I get it like I want it, I blow it dry to set the colors. My preferred finish after painting, satin Minwax polyurethane brushed on heavily over the entire carving. I let it soak in for a few minutes and then blot off the excess with a paper towel. One coat will give you a matte finish with colors that pop. If you try to do additional coats, it will start to look plastic. All of this is not really complex, but it does take a little time to make it look good. Your carvings are worth the effort! I hope this is useful to you in your painting! Thanks for looking.
