graphite on stonehenge 21"x13"
One thing I share with my students is the importance of drawing study. It is something I try to dedicate time to regularly, I've been working at incorporating a daily drawing practice for a long time.
I can't always study the live model, so I like to do master copies when I'm not drawing still life. I created a special large drawing board dedicated to master copies and bargue plates and it sits on my main easel whenever I'm not painting. Since it's in main view whenever I enter the studio, and I'm using a sight/size method, I instantly see issues that need correcting and I grab a pencil and begin to work. Sometimes I'll spend hours, sometimes ten minutes. This piece took a couple weeks to complete.
here is a wonderful site to learn about sight size drawing:
