Hi Josefe, the good message, you aren't doing anything wrong, you have been following the tutorial very diligently, and I actually see your lines developing in a good direction.
The bad message, you probably can't see that direction at all and are confused. The reason for that, the tutorial on this site is extreeeemely abbreviated and condensed to fit into one page of text and a few pop ups between drawing sessions. Everything written in the tutorial is true, essential and important, but learning to draw from that is like learning to fly a plane by following the instructions on the back of a cereal box.
I recommend the Human Figure Fundamentals course on
proko.com . The free version is entirely sufficient. It follows basically the same drawing concept as the tutorial on this page, but it takes itself 32 hours of videos, with instructions and practices to follow, to fully explain the concept.
I could try to give you individual advice on your drawings, and how to progress, but I would mostly quote from memory from Proko's course for these first steps, so it probably just makes more sense to point you towards the original source of most of my basic understanding of the human form.
