After completing all the details in the painting I made a fine outline to enhance the details with the help of a 0 number round brush and allowed it to dry completely. Then I applied a protective coat of transparent varnish easily available in market, just to protect the painting from dust and other wearable factors.
Now the painting is ready to be exhibited! If you are using a canvas pad or canvas board you can frame it and now your acrylic painting is ready for display!
