These are already so nicely done! If I must say one thing about how to improve... I think you may introduce more "twist" to the volume. For example look at the legs in image 2 and 3, and the waist/bottom area in image 5, they may appear stiff, you can introduce *some* twist to them so it's more energetic. Now they look they could use a little bit more "strength" if that makes sense :D Still very good gestures... I'm in awe, couldn't do this myself XD.

You've got nice strong lines there and they're definitely gestural, but a bit mixed with structure as well making them 'bumpy.' I would try simplifying it a bit more first and then build the structure on top to refine the drawing (if that's what you're going for). I've done a quick paint-over to show what I mean. Then you can measure proportions etc from here before adding detail.

There is definitely a lot of character here, which is great. The proportions are a bit cartoonish, you tend to make the legs too short and and feet too big. Also you tend to exaggerate every curve rather than just the curve of the pose/spine. I'm sure not all of the female models had bulging biceps like this so don't be afraid to throw in more straight lines!

Hi Renaldi, Your gestures have a lot of charaacter to them! What I believe you can improve upon are lines. I see a lot of sharp lines with are adding that character to your drawings but you need to balance them out with some slow sweeping lines. If you find a line to be somewhat straight don't try and give it a curve rather make it more straight, try and amplify the function of the line. I also feel the proportions are a bit off so keep a look out for negative shapes and overall proportions of the figure. Anyway these are great drawings and seem pretty animated, which is always a good sign!

very nice drawings :) but I think you got caught up in drawing each details and makes the figures look stiff, I think if your studying gesture you should focus on the overall flow of the pose, try to use more simple shapes. hope that helps :)
