I don't know, I need a starting point. As I said th sticky and some other guides on /ic/ explain well what path to follow with books. I need something similar with video tutorials/online courses.
This is more or less my shitty level, left is my first attempt at Huston heard and right is a figure from immagination

The heads are a bad first try at the Huston construction method. The body figure is my attempt to deay from immagination without using construction. I know it's all shit, but seeing my current level, what would you guys suggest me to do? What book/course etc. should I start?

These are some studies I made some days ago. The heads are some badly first try at doing the Huston method.
The body on the right is a drawing I made without reference nor actual construction.
Now, I know they are shit, but seeing my level what book or course would you suggest me?
