Done entirely with my off hand.
Not too bad, but mostly because of my super-sketchy style. Had a few revelations on how to hold the pen, though long curves are still impossible. Inking would be much harder. Though I'll bet if I did this every single day for a few months I could get it almost as good as the right. Hmmmmmmmm....
Right is recovering. Had a setback last weekend, but hope to be back at it this weekend, restore CF buffer pages, then maybe take another weekend for personal projects to make sure all is well before opening commissions again.
