This is my Sailor Messier 72 performing her second attack, Supernova Barricade. This attack shields at first, absorbing her opponent's attack and adding power to it at an alarming rate. Then it explodes taking the opponent out.
I think this is the best semi-motion pose I have drawn in a long time... I have my Christopher Hart "Manga Mania: Magical Girls and friends" book to thank for it... The pose would not have looked half this good without it.
