Another one of my original concept designs- Mockingbird done in Avengers movie style.
As shown below, my inspiration came from a mixture of costume designs from Maria Hill, Black Widow, and the standard SHIELD uniform. I'm hoping they put her in the next movie for a bit of Hawkeye, Black Widow love triangle, or at the very least a character in the upcoming SHIELD tv series.

For the figure I used a movie FF Invisible Woman from ToyBiz, repainted. I then drew the SHIELD emblem on her chest with sharpie. Her goggles are from a movie Cyclops figure that I cut into two lenses and gave a silver trim, and her batons are made from small wooden dowels painted silver. All in all, I think she fits into the universe's look.
