Painting with Glazes

I've decided to try a series of portraits in acrylic. This one is actually done with a layering of glaze colors. I purchased some glazes quite awhile ago and wanted to try them. I started with an underpainting of warm tones, and then began to build on top of them with darker variations of browns and added blues to the darker sections. They no longer make the glazes I used, but I did find Ceramcoat BASE GLAZE which can be added to any acrylic paint to give the same effect. I found this at Michaels.....
