Day 2

Hi there! Your poses are pretty good for a beginner! Especially the bottom right one, though there are a few things that can be improved, the most important one is that you don't seem to be using any construction for your drawings. Instead of outlining the shape of the body, try drawing the line of action first, then placing circles for the head, chest and hips and finally placing the limbs, then you should have a better base to define you pose (for more in depth explanations, you can complete their 15 mins introduction tutorial

An other thing is you line confidence, it's always better to sketch with big stokes, often using your whole arm, not just your wrist, to move your pencil on the paper, with a little practice, it should improve your poses by a lot as well

Also it's a great idea to be using a non-erasable pen, like you seem to be doing, so you don't have the temptation to use an eraser and you can be more confident :3
