>>3789852Gesture is just composition applied to figure drawing.
Animals, Anatomy, Environment, Objects aren't really in line with everything else because they aren't actually the fundamental building blocks, imo.
Also for Objects I'd rename it to either Hard Surface or Mechanical for clarity (if that is your intention).
Personally I'd add another topic called "Subject Matters" and put in Human Figure (maybe with gesture and anatomy underneath), Objects and Environment there.
