Robin Moses' Rainbow in the Dark

I began with a black polish with a little tiny bit of glitter in it then used my acrylic paints to create the rainbow.  I unfortunately make very thick lines so I ended up painting the next colour over the one before it to reduce space.  I did a pretty good job on the purple (the last colour) to try not to take up too much space. Now that I have it beside Robin Moses' original, I remember I did it up side down.  I also added a bit of sparkle to the rainbow with Sally Hansen Xtreme wear 180 Disco Ball
