The ping pong balls

In term 1,i have done many things.One of these is drawing emotions on 40 ping pong balls.
First,i drew 20 emotios on drawing block.After that,we are told to transfer the emotions onto 20 of the ping pong balls.I chose colour pencils as my colouring material.
After the 20 ping pong balls,i continued with my another 20 ping pong balls.
This time,we supposed to improve the emotions we had drew on the previous 20 balls.
The reason i chose colour pencils as my colouring material is because there are many choices of colour i can use to drew the emotions and it was easier to colour the balls if compare to other materials such as water colour and acrylic paint.
