Foot

Nice foot. Keep in mind, almost any view the foot is seen as a triangle. In your drawing, you should see a bit more of that idea. From this picture, I can not tell how you are on the whole figure, but I would guess you figure work is good. I would like to see your work using the figure. In the meantime, work on anatomy - muscle & bone structure. Also, include feet & hands. Do many drawings in these areas.

Practice makes better. You will be surprised by how your work will improve.

I really love the toes. They look realistic and in proportion to each other. Shading is nice too.
I would take a second look at the angle of the the foot where it connects to the leg. It seems to be at a slightly, unnatural angle.

Maybe take a look at how the foot is angled--where would the ankle and shin be connected from that vantage? In what direction would the leg go?

Maybe use a friend's foot for reference or put your phone on the floor and take a picture of your own foot.

nice work!

keep it up!😊
