Hey Philippe! Great job on this, I really wouldn't change much about your robo bean. It's definitely correct, and you're understanding the anatomy of what's happening. That being said, yours lost the energy of the post. I think the next step would be to draw it with more gesture, and to simplify your shapes. I did a very quick draw over of what it might look like if I were to draw this post in a figure workshop. Sorry if it's not that clear in my example, but what you drew can be explained in two very simple lines. Two mild C curves to show the gesture of the body, and then some overlapping Ines to create some structure. This is really one of those skills that will take years to master. A good exercise to practice this is to do draw overs on poses. This makes it so you don't have to worry about anything other than the structure / gesture which allows for more precise practice. Hope this helps!
