Good practice! When it comes to proportions, there's a bit of a tendency to make the torso larger, so being aware of this can help keep your eye on it as you continue to practice. It also helps to break up the torso into more defined areas, especially looking at how it twists and turns in the reference. With rhythms as well, you want to be careful with parallel lines or simpler box shapes, as they can remove the dynamic flow of the drawing. Try finding different start and end points for these lines, as that creates an ebb and flow as one line leads to another. Also varying the type of line, such as curves vs straights, can help bring in more variety. Hope this helps, keep up the good work! :)

Looking good! Keep going

The light and shadow is the first image in case that’s not clear. The second one is the hierarchy image

Both of those things will develop over time with lots of consistent practice. You're on the right track! Focus on gesture and designing interesting shapes, and confidence will come!

I think maybe working up to the boots or a complex subject would help. Try doing the project even more basic, like with the first lesson with the pear, do that with only straights, then do it again side by side with CSI. Then try a subject that is a bit tougher, like the snail or even a shorter jump in complexity like a different fruit or veg but a bit more complicated than a pear.

I like your values shapes! I think especially since this is digital you can push the darkest dark a bit more.
