Some hand sketches ranging from 1 minute to 10 minutes each.
I like the white highlights on the hands. It gives the drawings a sense of depth and realism. You have a very unique style and sense of lighting.
I would like to know which ones took 1 min and 10 mins. you can put that under each drawing so your progress can be further evaluated. Also, what type of materials are you using, colored paper or plain, colored pencils or charcoal?
Nice drawing upper right. I think it feels the most complete on this page but you are clearly on track with discovering what works for you with the entire page. I would like to see more. Keep going.
