Hey @age, These are pretty fun poses and drawings. Make sure that you don't loose the gesture of the limbs and body when you add these shapes. I noticed the tubes that you used for your limbs are very stiff. Try to add some gesture to them to give the body some rhythm. Also, make sure you tilt the torso back, unless the pose is bending forward, and that the pelvis is tilting down. I did a quick sketch to show you what I mean, I hope it helps :)
