Hey, @Mirelle Guillén, thanks for reaching out! :) I think you’ve done some really good work! Solid forms, clean lines, good sense of structure. Way to go! I agree with @Anna Sch, taking a little side trip to the Figure Drawing Fundamentals course could help you see the “bigger picture”. The lesson on Landmarks of the Human Body is certainly a valuable one, and you might also check out these lessons on proportions: Human Proportions – Average Figure and Human Proportions – Cranial Units. By the way, the proportion diagram Stan provides under the "Downloads" tab in these lessons can be a pretty handy tool to keep and consult as you work through your studies even in the Anatomy course. As far as the ribcage is concerned, I really don’t see anything that needs adjustments right now. Good job! Regarding your thoughts on how to draw the pelvis, yeah, I can tell from experience that it’s probably one of the most challenging parts of this course - so nothing to worry about if you’re having a hard time with it at this point. Based on this set of drawings, I’d say you already understand the overall forms of the pelvis and its main relationships with the other elements of the torso, which is great. Adjusting the size and spacing of these elements and building up your confidence on how to match a believable sense of structure of the torso could be just a matter of getting some more mileage and familiarity with the anatomy over time, study and practice. I’d say you’re on your way. Two helpful little things to remember: 1. The pelvis’s height is about 3/4 of the ribcage’s. If we take the cranium as a measurement unit (as in Hale’s cranial units system, which Stan mentions in the Proportions lesson in the Figure course), the ribcage is about 2 craniums tall, and the pelvis is 1 + a half. Having this info in mind can be a good quick way to visually check the size relationships between these elements. 2. The distance between the 10th ribs and the Iliac crest (in other words, the space between the ribcage and the pelvis) is nearly about the width of the person’s hand. In a torso sketch such as the ones you drew here, you could visually estimate what the person’s hand width could be, and then adjust the distance between the ribcage and the pelvis based on that estimation. (The proportions diagram I mentioned before nicely illustrates these two tips). From here, maybe you could take some time to do a little self-assessment and see if you can adjust these sketches by yourself? If this still can’t help you solve your current doubts, feel free to call out again. Best of luck!
