Having looked at the original and the other shot, again, it seems that you were using a large, diffuse light source and had the glasses on a shiny surface, while in the other example image a focused or point source was used that lit the surface they were on THROUGH the glasses, causing the colour and shadow to appear like they did. In the image that Alf processed the shadows are fainly visible, but they are soft-edged, while the shadows in the example are sharp and clear, being cast by a point source. You might also need to surround the glasses with black card to stop reflections of light back onto the surface and give the glasses a darker edge for definition.
