One of my practices of drawing with left-hand (my non-dominant hand). Due a problem with my right arm that makes me unable to do daily things normally (including drawing), I've needed to train my left hand and learn to be ambidextrous. It's difficult and I do things slower than usual, but it's just temporary. That's why I haven't submitted drawings on my galleries in a while.
I've been sharing some few left-hand sketches on my Telegram channel: https://t.me/panda_paco Also there I shared on the comments of this picture its process video.
