Bishounen Skeleton Silhouette

I created this because I could not find an anatomical reference for an anime or manga style male character who was slender, narrow-shouldered, and not muscular. I started with references of a real male skeleton and silhouettes of some bishounen I thought had particularly attractive proportions, changed the pose, drew a skeleton to fit the silhouette, put it through a round of critique, then did this final draft.
