    The biggest complication that I face are the positions of ulna and radius when the hand pronates. They overlap in some weird way and that ruins my day.

      I have quite a few images in my second book that show a variety of movement of the forearm, from supination to pronation, with arm extended and flexed. This might help you: with the forearm in supination, radius and ulna are parallel, both extremities of the radius are on the lateral side of the arm. When the thumb is on the outside, radius and ulna are parallel. When the forearm is in pronation, the bones of the forearm are crossed, with radius going over the ulna, the proximal extremity of the radius (at the elbow joint) is always on the outside but the distal extremity of the radius (at the wrist) is now on the inside.
      I short: when the thumb is outside (supination) the bones are parallel, when it is on the inside, the bones are crossed.
      I hope tis helps

    I'm buying this book next week, I need a reference for anatomy and so far I think this is the best when it comes to details. Is there a practice study that comes to this book? Just curious, there are many approach to drawing anatomy but I think I'm somehow getting loss at the techniques. I'm using Michael Hampton technique for now but his technique is more on a wire frame and mannequinization, I want to draw an actual skeleton to deepen my understanding of the bones so when I try doing the origin and insertion they'll be close to accurate😅.
