Because the first images of the metal foil relief were in a night light setting here is another little series with more daylight, showing her doing the colorful pieces of cloth trick (presumably after some magic involving a rabbit).  
I’m generally happy with how the figure turned out, but it is also somewhat reaches the limit of what is possible with the limited number of colors of the eddings I have to paint the foil. Trixie has many shades of light blue and there is only a single light blue colored edding. I managed to get to slightly different shades by first coloring parts of the mane white and then paint blue over it while in other parts the same blue color is applied directly on the metal. I’m afraid there are some ponies not possible to be done with the existing colors, but there will be more.  
There are several different versions of this picture taken with different light and camera settings.
