Tsubaki the Super Soldier

In one of the many possible timelines, military cadet Tsubaki Yayoi volunteered for the Library's Super Soldier program. Within weeks, she had obtained a massive, inhuman physique and supernatural reflexes. Through the years, Tsubaki would earn the rank of Major and become known as the Library's "Red Angel", a riff on her Iron Tager-esque physique, red hair, and feminine features.

Just wanted to do a head sketch, and ended up doing a lighting, pen control, and anatomy study. :/
