That's a very interesting effect you have created...it looks like you have used a very low DOF to take the picture and then used some type of convolution filter to amplify "local intensity"...eg, pixel values in the filtered image are remapped via the following rule:

F(x,y) = (G(x,y) - min(N,x,y)) / (max(N,x,y) - min(N,x,y) );

This would give the effect of "flattening" the image and also bringing out contrast in all color ranges.

If you are using Photoshop to do this post, I would be very interested to know exactly how you are doing it...because I would have to write the program in C++ to do the same thing.

As far as artistic C&C goes, I think that the first two are by far the best, and it is mostly the technical effect that makes them interesting because the subjects are a bit simple. This effect does not look so good on the child because it mainly just accentuates his veins which look odd. I don't like the cross dresser picture at all.

Your level of understanding here is admirable.
