Would you give more credit to your brain or to your hands for your drawings?
hmm... interesting question
even though I’m predominantly left handed, I can draw and write with my right hand if I utilize a mouse.
Our family computer used to have the mouse located on the right side, so out of necessity I learned how to use my right hand... and then it simply stuck with me to this day.
Before I ever got a drawing tablet I spent several years making digital art with my right hand only.
I think drawing starts in your head with the initial idea, the layout and planning of whatever it is that you want to create.
Your hands are more like tools that your brain utilizes, but once you learn how to do something with your hands it’ll indefinitely stick with you. It’s your choice if you then wish to further refine the skill or not
It always starts with the brain however, so that’s my choice
