Life Portrait - My Grandma

I've realized for some time the importance of working from life but until recently didn't have the space to properly do it. But now with the new studio I do. So in between my many other projects, I've been trying to fit in a portrait of my Grandma entirely from life. She was kind enough to agree to my crazy request and came by today for the first sitting. This photo shows the rough-in for my initial drawing. Once I've completed this drawing, I then plan on creating a painting of her entirely from life. There's nothing better than painting/drawing from life.

(At this stage, I'm only focusing on large shapes and overall proportion)
