Additional practice

Hello, Shadonis, and welcome aboard, and how are you doing this afternoon? I know, I think you're doing a great job on capturing the relationship between the ribcage and pelvis, food for thought while retaining the guts whilst preserving the sparks of life in your loose lines. I feel that the lines of action could be a little bit more push as far as you can go, so how about you please go for 5 more minutes of 30 second figures of various states of non-nudes, without being too distracted by the real details.

The reason is because, if your goal is to make your edges and relationships less stiff, but more fluid but lively. For more details on your practicing goals, then I suggest you kinldy look into Daniel Coyle's The Little Book of Talent, on Amazon, even if you're gonna see a bunch of unknown boxes.

Good luck from me to you.

OK, very good, systematic approach. You seem a bit unsure what shortcut to use for the pelvis. Generally you can start either from a sphere at the size of the buttocks and groin, which is a good starting point for finding flowing lines that indicate the thighs, or you can use a box as shortcut for the pelvis, which makes it easier to indicate perspective and orientation of the pelvis in space.

On those drafts, in which you got done indicating the pelvis, your shortcut is way too small and flat, though. The hips are at least as voluminous as the head.

I like, that you don't hurry your 30 second practice. You could consider doing a warm-up to your warm-up, and just draw a bunch of ovals, so your hand gets used to the motion, and you develop a cleaner line for them. When practicing ovals or circles, drawabox.com usually recommends always repeating the oval twice in one fluid line.

You have the right idea. Just as some pointers, id recommend switching to less circles and ovals for construction, and instead use harder angles to suggest direction better.
Our spine tends to curve in an S-shape and seen from a profile, the angles of the shoulders and hips must converge.

There are no perfect proportions!! There are proportions that are aesthetic and some that arent. Keep searching different ratios and youll eventually find your way:)
