His site recommended that you start with his Vilppu Drawing Manual - Basic figure drawing. It's focused on figure drawing, do the exercises from reference, then from imagination to deliberately practice that skill since that is your goal. There's also an accompanying DVD series going through the book too, you can find it on RuTracker or Bilibili. Vilppu Studio - Drawing Manual. Use both the book and the videos or whichever you prefer.
