like you, i've been painting with my left hand. as a former abex painter, i never included drawing in my artwork. now after my injury, i find myself drawing and applying paint with my left. now, there is a "looseness" in my gesturing, i would've never tapped into from my right hand.
my "artistic father", W. DeKooning, often drew left handed and sightlessly. i challange you to continue using your left even after your right fully recovers. i'd love to know of your progress; my email is [email protected]
if you care to share.
