Carl, you would not have to both make sides of the robot equal because they are singsong, and would have to make the legs different, because one sees as if the robot is going away to fall thus. I would advise to you first to make the lines and despues shade the drawing. Steps: 1. lineart, to define it and to refine it as you want that it is 2. to fill it with the colors base 3. To choose a direction in where the light falls to him and to choose clear and dark tones of the color base and to make blocks of shade and light guide 4. to refine to the lights and shades 5. to put dithering to him if you need in the lights and shades 6. Anti aliasing.....tanto in the borders of the drawing like in the shaded one You would have to advance a little so that you receive more aid:)
