This design was inspired by the 2015 movie Cinderella movie. I absolutely ADORE the crisply faceted look of the glass slipper int heat movie, and I thought "Wouldn't it be cool if I cloud paint that slipper with a dark background (the way it is depicted in a lot of the photos online) on one accent nail, and make the other nails like a see-through glass with a sheer, bluish tint? So I searched YouTube for ideas, and I found a design by NailedItNZ.
She did an excellent nail design of the 2015 glass slipper. I was soooo jealous of how cool it looked and wanted to re-create that. So I studied her video. Then watched another video of a sketch artist actually drawing this same exact shoe, to get an idea on lines, angles, facet cuts and colors.... I drew a tiny version of this shoe, freehand, on some paper. Then put it behind a plastic document protector and went to work painting over the design on the plastic. I basically made a "decal" using clear top coat as the backing, then painted the slipper over that. I used a TINY detail brush to paint the outline of the slipper and the facet cuts. Then I used a tiny dotting tool color in the tiny sections with dark and light blue, to give it that sparkling "faceted" illusion.
For the nails, I used clear acrylic tips, for that "see-through glass" effect. I didn't have a sheer, light blue. To I mixed clear polish with blue, and made my own. Painted that over the other nails. Then taking inspiration from a Robin Moses Cinderella nail art design, I painted magic swirls and twinkles with a detail brush on the other nails, using white and silver polish.
Looking back now, I wish I had made the other nails an even lighter sheer blue, and maybe covered less of them with the magic swirls, so the glass effect would have been more noticeable. But I think they still turned out quite nice. :)
