I have been drawing these little bird characters off and on for about 6 years. I call them Strange Birds (kinda like me😉) and when I draw them in mass quantities they seem to put me into a semi-meditative state. While in this state I feel less pain, less anxiety, less depression and less grief.
Here is an example of a partially finished piece at the beak colouring stage. From here I will move on to add colour and more personality to each bird. Even making colour decisions has a calming effect.
