Could someone give me some feedback on these digital studies? I think I did the boat / Sargent / Leffel studies a bit wrong (I kept the 3 values but I don't think I broke it down properly -- I was basically just observing and drawing what I saw.). For the Rembrandt, I first sketched in the rough proportions, then tried to break down the shapes in the middle picture, and then I went back and tried to refine that. I think my proportions ended up being a bit off. How could I have executed this better? I think I'll give it another go and try to match the value of the shadows of the coat to the shadows on the head. Maybe I should also do that for the red part of the shirt and the things he is holding too?

Here are my attempts after the demo.

The fourth interpretation made a lot of sense - stabilising the composition and grounding the character.

I’ve completed a couple here. Had a ton of fun with these!

Five minutes in and I'm like, 'yes those details got me again'. Haha! Anybody else?

Here a bunch of thumbnails that took 2 minutes each

Thank you for the demo. Small studies helped a lot to focus and warm up to the three-value study. I had to push myself out from my comfort zone to done this task. But I am glad, I finished a new study.

Thanks Proko, Its very well explained!!!

thank you I think this is going to help me

Thank you, Stan.
