Not that I want to see a topless man, but I think this would have worked better shirtless, with the moved panels still resembling the area that was moved. Also, the anatomy portion looks too fake. Actual lungs and a trachea would have looked cool. I love the idea, and it looks like you did a good job with the original image.
Maybe even instead of shirtless, you use a button-down shirt that you hold apart in the middle revealing your organs.
