Well I suppose they're not too terribly realistic, but I tried! I went for a very dark, stormy background, and added random patterns for the lightning. The lightning bolts almost look like veins or nerves.
I also wanted to add a bit of color so it wasn't just white strokes on top of black. I sponged on some purple and blue, and it almost looked like galaxy nails before I added the actual lightning bolts.
I started by using a base coat, and then painting one coat of Wet n Wild Black Creme on. Since I was sponging, I didn't even wait for it to fully dry before moving onto color. I then lightly sponged on Wet n Wild Through the Grape Vine and I Need a Refresh-Mint where I was going to make the lightning bolts.
Since they were a little bright, I added a layer of Sally Hansen In a Flurry, since it is a sparkly dark jelly. I also wanted some shimmer! I then free handed the lightning bolts. They looked a little plain to me, so I went back and sponged on a tiny bit more color. I was satisfied with how it looked then, and added my Seche Vite.
This is another first attempt that I love! They really do remind me of galaxy nails, and they didn't take as long to paint as I thought they would. I suppose sponging the color on before the previous layers dried help speed up the process.
