I erased the red paint of the arms and repainted some parts in a mix if blue and black acrylic paint.
I painted the torso and chest with the same mix of colors and let them dry for 12 hours.
Meanwhile I removed the hair of a Marvel Universe Rogue and sculpted part of the hair and completed the look with a GI Joe Scarlett's pony tail.
I painted the hair with a mix of oil paint and painted the eyes, mouth and eyebrows.
For the final touch I added a red fabric belt and a sword of some GI Joe ninja figure.
