"People come and go". That is a constant thing in life. We will meet new faces along the way, new learning to gain and experiences to encounter, but none of which has the consistency to STAY. Family on the other hand has the opposite. Will scold you, hurt you and a lot more things, but family never leaves you no matter what. 
This drawing of yours really displays enthusiasm and overloads with love for your mother. Every detail is perfect. From the shadings to the over-all layout, I can sense every bits of emotion from the drawing. Not to mention your mother is really lovely. I , as your fellow artist couldn't be more proud of what you have portrayed in your craft and I am pretty much sure that your family is too. All I can say is that, you keep up with your work, and always stay humble and keep your feet on the ground.
