I love the new cortana figure that mcfarlane released but there were of course things that bugged me. for one the base was very lackluster. and since the figure is translucent like the halo 3 style only with some paints over to defy her face. I wanted to add lights into the base like the other cortana. I dremeled out the 3 places around the top of her base and used the leds and other pieces from the other cortana base and combined them together. on the back of the base i put the switch into the base so u can turn the light on and off. then for cortana i did a repaint on her face redoing her eyes and lips and adding pieces to her hair to make it more accurate to the game. I hope you like her
