First Week

I think you did good on the proportions side.
10 min study is missing some strategic lines that would convey form and tridimensionality of the figure. Ideally some basic shading would also help convey this idea.
Highlight the pelvis mass and the chest and show the front and sides of your figure.
I made a horrible correction using MS paint but I think you get the idea.

Try building off placing the rib cage and pelvic bones first. Knowing where the top of the sternum is can really help you place the head. I can see you’re working off eyeballing landmarks. If you start with the larger forms it will make it easier to find and place others. Nice work!
