Hi Brett, good stuff I'm inexperienced too, but thought maybe this feedback would help. For the woman in the middle row on the far left, I actually see the gesture of the torso as the opposite curve. Like her body is curving up, not hunching over. Something like what I attached here. Take a look and see what you think!

Hi teebo, good effort! The best advice I can give now, be bold! Go for big sweeping lines, don't worry too much about proportion and capture the energy of the pose. Here's a good video Proko did with Mike Mattesi (Force drawing) that should help with the kind of strokes to aim for. And don't worry, you won't have them flowing and accurate like Mike's straight away, that comes with lots of practice ;) Those reference poses you have are great for gesture btw!

Great job mate! I would say you should try to clean up your lines a little. Try to use softer graphites or charcoal for gestural drawings, it helps a lot :)
