Interesting experimentation.

The third image needs work because the "gross stuff" reads as being in front of the shirt. You need clean, precise masking to pull that off. I like to use the pen tool and convert that to a mask. Also, zoom in to about 200% for added precision and use the space bar to drag the viewable image. A little bit of shadow cast by the edging of the shirt will complete the effect.
