Nice work on these robo beans. The bottom one in the 2nd picture is the strongest one in my opinion and it also has the best stroke width variation, and it looks overall very fluid :) I have a few things I'd like to critique, and I have included some examples where I added red lines for reference. It's up to you whether you think it's helpful or not :) 1. The first bean in the second picture looks nice, but the way you've connected the pelvis and the ribcage made it a bit confusing, and when I first looked at it, I thought the the larger plane of your ribcage was meant to be the side, not the back. I've included an example of which lines I'm talking about. Also, I think we might be seeing a little too much of the top plane of the pelvis. 2. The 2nd drawing in the first picture, I can tell you've tried to exaggerate the twisting, which is good in my opinion, but I think it might be exaggerated a bit too much. In the original pose I think we're actually seeing the side surface of the ribcage on the opposite side of where you've drawn it and I think that might be a pretty long way to twist to the point where we see as much of the other side as you've drawn it. Either way, I am just pointing that out and adding a example. 3. In the first drawing of the 3rd picture, you have tilted the ribcage down a lot and straightened the foreshortening, and, I also feel like you might've distorted the box of the ribcage a little to much in it. This may be an intentional exaggeration, and I think that's alright, but either way, I feel that part of the exercise is also working with landmarks to find the placement of the pelvis and ribcage underneath everything, even though making them a bit bendy and lively is nice. Also remember that the arms and shoulders can move a bit independantly from the ribcage. Either way, It is a difficult pose to figure out, and I'm not completely sure I did it correctly either, but hopefully the example is clear enough to be helpful. Hopefully this feedback helps :)
