There are hundreds, maybe thousands of variations on this plot so it would be hard to say where it really originates from. It was decent but invest a bit of money and time in to pinky counting, your double needs work.

It needs a little fleshing out. Right now it lacks motivation. It's a color change and a back revelation but one doesn't lead to the other. It needs a good set up for the ending.
