I second what xun says - the 2 minute sketches are brilliant. They are full of movement but also crisp and clean. On the contrary, many of the 30 second poses look rigid, overthought and scratchy. Not all of them, I do think that poses 9, 10 and 17 have a wonderful sense of fluidity to them. These are probably more successful because of the confident, long lines that you use for them. To address the rigidity, I would suggest that you keep practicing the 30 seconds but without worrying about how they look or if the proportions make sense, just look at the pose and try to summarize it in three to four confident and exaggerated lines. Stop after every 5 to 10 sketches and evaluate what you like and dislike and keep this in mind as you do the next 5-10 sketches. Then repost here again :) I hope that helps!

You definitely nailed the 30 second drawings, the figures are so fluid and dynamic. Fortunately, this fluidity and dynamism seems to have translated to the 2 minute sketches as well. I particularly love the long legged contrapposto one - it looks like professional fashion illustration template! However, I agree with you that the 2 minute poses generally lack proportion and anatomical accuracy. To me, this simply indicates that you should move on to study the bean now which will aide your issues with proportion. As you clearly have mastered gesture, (I can offer you no critique in this regard), I wouldn't spend too much more time focusing on it :)

These look amazing! But from watching the gesture critiques video I would posit that they are perhaps a bit too contoured and perfect for gesture exercises. They feel very thought out and lack the looseness and exaggeration associated with pure gesture exercises. That said, to my eye they are full of movement and show a knowledge of anatomy I aspire to have. I really love the last one in particular - I can feel her falling! Well done.
