My friend @spintwister and I decided to do some live drawing to kill some time. Using the old bottle and cans that I used to have some failed drunken art experiment as models, we set them up and let it pose for us for more than an hour.
As usual, drawing the contour.
Then did some shading using HB pencil.
Added some more shading using B, 2B, and 4B pencil.
Finally used 6B for the darkest tone.
