Excellent version of Iron Man, and a female version to boot! Your tech is just fine, by the way, well done. At first I thought this was the "Calhoun" character from the "Wreck-It Ralph" movie, I stand corrected.
Your reference to the Neil Diamond song (and the '80's movie) is an original touch as well, very clever. I doubt anyone else has thought of it. I would imagine your Iron Girl has in addition to her "heart light", a glowing index finger as well.
I seriously hope that's there simply to power the suit and not some other reason, that would be sad.
