The version posted above is 100 dpi. I then experimented with the photo in Paint Shop Pro 8. The picture below was done with the Virtual Painter Collage plugin, but I don't remember what settings I used. Again, it would be an ACEO size if printed, but the version below is 100 dpi. I also had to run Sharpen on it when I reduced the picture size to capture the original detail.

For the last manipulation of the picture, I ran Artistic Effects, Colored Foil. I started with the Custom 4 setting, kept the default gray (RGB 192) color, kept the default Angle of 133, changed the Blur to 17 and changed the Detail to 24. I think it gives a cool, funky effect to the picture. Again, it would be an ACEO size if printed and the version below is at 100 dpi.
