This robotic creature is truly a sight to behold. Its spherical head and long cylindrical body are out of this world! The two large, red eyes and thin mouth give it a sense of character and personality. Its two robotic arms are thin and its body is covered in purple armor, making it look quite strong and resilient. I'd suggest coloring this creature in blue, purple and red for a more vibrant look. By coloring the arms in a darker hue, you'll create more dimension, while a light purple for the head will bring character and depth to the drawing. You could also color portions of the armor in yellow to really make the drawing stand out. Add some white and black highlights to create extra interest.
