The thing I love the most about RWBY Justice League Part 2 is that the small details of their new design
Ruby's body has lean muscle all throughout except for her legs and your shoulders, they are buff (Track/Runner body with the muscle of lifting Crescent Rose). She lost her baby face and looks more similar to Summer.
Weiss has a lean body but with dancer/ballet posture. Elegant like a princess but a hint of semblance of Winter. However she sadly does not take after her mother.
Blake is buff but still on the lean side with a gymnast body, strong legs and thighs for jumping and upper body being slightly prominent. Plus she is thick (Praise the Bellabooty)
Yang being very buff all over (Yang Muscle Supremacy 💪). You can tell she lifts, does hand to hand combat (Boxing and Kickboxing). She also lost her baby face and her jawline is chiseled. The best way I could describe her is that she has the physique of father and the face of her mother.
