Hey, @alek_, I’m catching up a bit late, but hopefully still in time to share a little feedback. The previous suggestions our fellows made about exaggeration and spatially-oriented forms are definitely valid. I’d add one more thing: if you're having trouble understanding the anatomy in order to simplify the figure into a mannequin, try to let go of drawing realistic anatomy altogether and stick to drawing just simpler, geometric-ish forms. If it helps, try to “forget” that you’re drawing a real person and think as if you were drawing an actual mannequin such as those wooden posable figurines people sell in art shops. Simplifying in this way can make it more manageable to think of how the individual parts fit together in 3D space to create a compound cohesive structure. I chose two of your sketches to draw over as visual examples of what I mean - they’re attached here. Hope it helps! Remember to always start your mannequins with gesture so they won’t be stiff objects, but rather more like “animated characters” posed with life, gesture and naturality. And just one more suggestion: since this exercise is directly related to a course lesson, you can feel free to post your drawings directly in the lesson’s page, under the “assignments” tab. In this case, for example: if you go to Mannequinization – Structure of the Human Body, you’ll find the “assignments” tab right above the lesson description, below the video player (in the mobile site, also below the course playlist). Then, you can just create a new post there. Posting assignments in their respective lesson’s page makes it even easier for other students who are going through the same content to see and comment on your work. Although, of course, it's not a problem at all if you do prefer to create a new topic in the overall community to post your work instead of posting it in the lesson's discussion thread. These are options you have. Please let me know in case you have any questions. Happy studies!

Im still a bit confused

Exaggerate. Some of the poses, the reclining figure shows it the most, suffer from lack of dynamic energy. Overdo it so everything in your head is on the paper then consider eliminating things. Don't edit your imagination, just the paper.
