Here are some scribbles from my left hand.
I started to practice drawing with both hands at the same time.
I've been studying old masters and one of the masters I've enjoyed is Augustus John's work.
I struggle with that nice loose flow I have with my right hand, so shading and drawing things like hair are hard, so I cheat a little and just my right hand for some of those things.
Practicing contour drawing has been such a huge help for me to break away from my cliché habits for drawing certain things. And for the first time I feel like I'm "seeing". Again I need to start pushing more story elements into my work, but that will come in time.
If you would like to see more, I have a "Art of" on Facebook where I have been dumping loads of my bad drawings.
