Sketches using reference. There is a little of everything, gesture quick driven drawings, Structural drawings aimed to find the geometry of the form. Color studies, get as close as the picture without sampling from the image. As always in life there are some good results and lots of bad ones.
Second, no reference
In a proper work piece, I believe there should always be some reference, be it form inspiration purposes or for understanding. Reference it’s not only about copying. In this case I leave out any reference and try to draw following a set of ideas. The results are very poor in content, I’m afraid.
