The Hogarth studies really do look good. It's great to see you sticking so diligently with the studies! Great work, mate. Keep it up!
Very nice Hogarth studies! They're beautifully rendered and look exceptionally accurate. However, I think it's important for you to switch on and off between working directly from your resource and drawing from memory. You really don't know how much of the information you've recorded in your long-term memory until you've tried recreating it on your own. So put all your books and sketches away and try to draw the leg, in various poses and from various views, from memory. Then open the book again and analyze the areas that you had trouble remembering. Do some more studies from the book while focusing on helping yourself remember it next time. And repeat. I know it sounds slow and tedious, but it's really the best way to make sure your learning what you're drawing and not just drawing what you see.
This weeks study sketch is the bottom the chalk cliffs of Rügen, which are rapidly falling apart apparently. Reference was taken from the newspaper.
I know that I should spend more time on the studies to make them more accurate and I will do that at some point, but right now they are just to get more used to working with my tablet.
