Drawing Process: Patch Job

There's not much to say about this. I used a few normal layers with an Overlay layer for the blue and orange lighting effects. Drew it in SAI at 8.5" x 11" at 300 DPI, using the Acrylic brush. I added the floor lines by creating a simple black-and-white circle design in Photoshop and then skewing it into the correct shape. GLaDOS's face was awful to draw!
