I’ve done a lot of side-by-sides drawing from my eye, so I thought I’d try a drawing from my mind.
The idea was to take a concept borrowed from someone else’s brain (It was: “Opening a present”) and to draw it with my right hand from my imagination and with my left hand from my imagination with some wait in between.
I don’t think I waited long enough. While I was doodling the right handed one I got a picture in my mind from a memory of watching a friend open a box, and it distracted me. The left handed one took a couple tries and a lot of closing my eyes to visualize it more clearly and draw from the imaginary image like I would from a photograph.
With my right hand I draw from much faster impressions, thereafter the memory of those impressions, and from the experience of physical sensations. I am unaccustomed to imagining things in that visual detail and having to maintain the gestalt in my mind for the duration of the drawing process. I will probably get better with practice.
