These look great! Here’s another way you can double check your proportions. Especially if there’s any photo distortion in the reference. Put down the reference and step back from your drawing for a moment to notice how the whole figure fits together. This will help you as you move along in your drawing journey. Keep it up! Thanks for sharing!

Hi @kotka, these are really nice! - It might help to find and add a horizontal halfway point (and do the same with vertical if you aren't already). To practice major accuracy more efficiently you could disregard the details and do a lay-in with fewer lines, then check your result right away. Hope this helps :)

Head looks too big and is throwing off the proportions a bit. Take a measure of the length of his head as a unit of measuring. Then count how many of those heads his pose is in length from tip of hand on floor to tip of toe. I like the box form shape you made for the shoulder. Those mother forms are great to use in constructing the figure. Also you can use negative spaces to check things. For example look at the negative space between the legs. It's shape is drawn slightly different from the photo. It looks like the angle of the lower leg needs to be changed. May be why that lower leg looks a bit too small. Negative spaces save my butt all the time. They are a great way to check the drawing for errors. Good work on Yoni! I hope the critique helps
