Quick sketching of a model - Linked-in course
Quick sketches
At the moment I am working on a number of drawing and painting courses via Linked-in. If you have a professional/business account, you can take lots of fun courses there.
Here are some results from the Figure - Drawing course. On the basis of a mobile, you need to draw a sketch quickly. Nice structure of the course, and really learned about the proportions of the human being.
