You're doing good really focusing on getting the whole pose together on a short timeline. Some of the poses are looking a bit flat, and I think it's because you're going "leg" and putting a flat leg shape where you think it should go, but maybe skipping over some steps in observation. I definitely recommend doing more of solid blocking under more complex shapes on shorter drawings. this might seem daunting, but it's often down to just laying down a few lines accross the body to really establish whether something's pointing toward or away from the viewer. If you're not quite sure, pick a direction anyway! This is part of learning to push poses, and also, you'll actually notice when you've guessed wrong the first time, and can correct it, instead of it just looking a little weird for mysterious reasons.
I think your best-looking drawings are the weirdest poses, and I think it's specifically because you couldn't make any assumptions and had to really pay attention to the pose, the more you can extend that attenetion to the rest of the poses, the better off you'll be!
