I think you're already doing great! My advise would be diminishing the time for each figure, by doing so, you lightly pressure yourself to get the more details you can get in that limited time, that helps a lot to get a basic anatomical shape and, with the remaining time, you can add minor details. It can be a gradual process, increasing or diminishing the time by how comfortable you feel with each shape. I'd say to start with the 30s poses, even if you get a single line at first, but if that line itself already shows the course of action of the pose, you'll be already off to a great start!
Hope this helps even a itzy bitzy
Best wishes!
You definitively got the basic idea! The lines are there and you can see the poses ment for each sketch. I'd advise you'd give another 30s for each sketch to outline the silhouette of the reference, ignoring minor details for now, like facial structures and such, only the outline, so you'll get how shapes and forms works for bodies. Little by little, you can integrate that 2nd wind on the 1st part, so you can learn both anatomical structures more easily and drawing faster, so when you feel more comfortable, you'll be able to draw a full silhoutte with important details even within the 30s intervals.
Off to a great start! Go go! :D
