Color Alive not working properly

It doesnt make the picture come alive if : 1) you put too much different colors. I colored the robot from Big Hero 6 and gave him different colors for different parts of his body. The app fails to recognize it. 2) my 4 years old daughter is not very good at coloring so she doesnt always color inside the picture and as a consequent, the app always fails to make the picture come alive.
