its interesting that you used the robot voice with a robot character the voice of the robot was kinda tacky he had no gestures for someone who is on stage and the use of a image as a background requires animated shadows ( were was the robot standing or was he floating on the image think about that) and one more thing when robots speak the light in their mouth sync with the voice so if the robot says five words the light blinks five times consider that too i really wanted to like this animation but it sucks sorry
