Thanks for the feedback last week. This week was an ideal exercise for me as I seem to have a problem clearly defining the line between light and shade.
For this exercise I went for focus and speed over spending a lot of time rendering as I have done in some of my other drawings on this course. I gave myself 15 mins to sketch in the frame and outline, then a further 30 minutes to complete it. I set the limit so I would focus on the key point of the task rather than spend time on rendering to complete the drawing.
Great exercise that I found very useful so thanks.
