The first is Tombow marker and ink on Yupo paper, about !8"x24".
The remaining two are Tombow marker and ink on 9"x12" drawing paper.
The model has an amazing, elaborate and beautiful tattoo of feathers on her back and upper arms. It was added to her body over the course of a summer.
I did all the one minute poses (the drawings in the background of the top drawing) with my left hand, and I also did large portions of the remaining drawings with my left hand (sometimes I'd forget, when coming back to a longer pose). The longer poses this day were from 15 minutes to 30 minutes long.
Using my left hand for drawing is not what I normally do. So I am much slower with that hand. But the most awkward part was that I am so used to setting things up for right-handed drawing that I placed my easel in a very unnatural position for left-handed drawing.
It's fun to switch to the non-dominant hand, and I find it also helps to diminish bad habits: seems like a fresher take on the subject matter.
Why draw with the non-dominant hand?
Well, it is a standard drawing exercise. The idea is that it frees one up to use the "right brain" to draw with. I don't know how valid this concept is, but it is a popular notion.
A practical reason, that PA is now bumping up against, is that sometimes you need to. Hands wear out or get injured.
Exercising that spare hand and arm and training and strengthening them, just gives the artist an extra drawing arm: a good thing.
