Commission arts for Hellsender of Chisame Hasegawa from Negima! in Marvel's Iron Man(Girl) suit.
It was very interesting and challenging converting the Iron Man suit into a lady suit. I must have revised it  like 10 times.

Character backstory:
Genius tech prodigy Chisame Hasegawa lives life on the fast lane. She is the owner and CEO of a multibillion and multinational corporation that researches and manufactures technology for science, medicine and defense. In public, she takes on the guise of Chiu-Chiu, a pop idol who is the official sponsor of Hasegawa Industries, while only very close and reliable persons know that she actually owns and runs the company, which was inherited from her parents who were killed in an accident. During a tour, she's violently kidnapped by a militant group in an attack that leaves her mortally wounded and forced to undergo a transplant with an experimental artificial heart. The terrorists force her to build weapons with supplies stolen from her company, but with the help and motivation of the surgeon who saved her, she instead builds an energy reactor that's implanted in her chest to keep her artificial heart running and a mechanized suit of armor to escape captivity. Soon, she discovers that her company and her resources are being exploited to aid and abet terrorists and despots. Eager to clear her name, the queen bee billionaire becomes a philanthropist and creates her own armor of hot rod red and metallic gold to rip away the web of corruption and deceit that her company is at the center of. Forced to juggle quadruple lives as a prodigy CEO, a J-pop idol, a bisexual playgirl, and an armored superheroine, she must keep her colleagues, fans and friends from knowing the truth...she is Iron Girl.
