Before and draw along!

Hi, I’m Han I would like to improve my ability to accurately measure the proportion of objects as they get closer/further. Not only that, but drawing precise lines from the same objects that are foreshortened as well. I also have trouble with curves placed in perspective (not necessarily ellipses or spheres), and sets of lines that are placed above/under others. The last main thing I have difficulty with is multiple objects in the same scenery following different perspectives, I have always found this topic confusing. Here are some images by Ruan Jia, Kim Jung Gi, and a couple of manga artists.

My Draw Along and attempt with a reference to draw the landmarks of the back! I first drew the gesture then tried to identify the same landmarks as the ones Stan drew.

My first attempt at identifying landmarks! Feedbacks are welcome :)

My attempts at animals simplified in shapes!

Hey Han, your gestures are pretty good, they have nice rhythm. Now I would try to be more precise with your shapes to show volume and perspective. We don't want the figure to look like it is made of noodles. I did an example to show you what I mean, and how you can move forward in your drawings, I hope it helps :)
