Allegra Lockstadt's simplicity

I never understood why drawings are not considered as important as paintings.
I came across with the left drawing by Allegra Lockstadt at the blog Minutiae and I loved it.
It takes a lot of work to achieve simplicity and it is amazing how many stories are told in this drawing since it's not precise who are the protagonists embracing each other.
I tried to find more of her works but they are dispersed in many sites. I got the right one at this page.
A touch of colour to stress subtle and powerful lines.
