Scanned line drawing & colorized scanned line drawing

This image started out as a line drawing from my sketch book. It was scanned and imported into Photshop. The line drawing was selected by adjusting the contrast/brightness. An alpha channel was created by copying the image, deselecting, pasting, inverting the image, placing it on a "layer". The lines were selected by deleting the background. On this clean layer I used selection tools (lasso, and wand) to select shapes. Shapes were colored using the fill bucket and gradient tool.
I was surprised by the reaction of several people to the line drawing - they felt it was the product of a troubled mind (and that psychoanalysis might be indicated) . However, some of the same people really liked the colorized version. The most common reaction to the colorized version has been a short quizzical laugh - which is the reaction I was going for. Just don't ask me what it means.
