First of all i really want to appreciate your mother's work and next i want to appreciate you because you are encouraging your mother's art, and for me the definition of art is deep emotions and sometimes we can feel that emotions in the art but there are great artist in this world who are not getting proper exposure. In this picture i will share my opinion as, i think the picture is saying about "Freedom Of Expression" and equality, our society never believes in equality what you see is they just pretend and when it comes to reality then you will see equality is just remained as an false saying, and in my opinion people who don't believe in the equality in my opinion they should understand their mother first because, we all cannot do what one mother can do and they always stood in front when it comes to sacrifices. Thanks for sharing this great and gem piece of art and wishing you and your family an great day. Stay blessed. 🙂
