Here's another of the simpler customs, a new paint job mostly. Maria's an older DCD figure, Wonder Woman series Agent Diana Prince. Since I saw that figure for the first time, I knew she'd be a perfect SHIELD agent.
My Maria is based on her look in the Mark Waid/Yeinil Yu Incredible Hulk book - rolled up sleeves, fingerless gloves, a gun by her side. As all of my figures, she was painted with multiple shades of different colors giving her a more lifelike look.
The only non Diana part, other than sculpted thingies (like sleeves and boot straps), is her handgun. That cool firearm holding hand came from Indie Spotlight Catchoo.
