Good work so far in capturing the entirety of each pose in your 30-second gestures; I think you are doing well when it comes to the shorter amount of time to capture the essence of each pose. Like you, I like the short amount of time because it pushes me to make decisions faster to get the overall pose.
Try keeping that same quickness when you translate to doing 2-minute poses, such as: making marks in one smooth, flowy line, keeping the pose simple like in your 30-second gestures, and capturing the overall form of each limb.
I think you are doing a great job, so good luck and keep up the work!
