I did this earlier on today but didn't want it:
It took about 30 mins even though the time says 8 hours and 2 mins. So, I made the highlights yellow, main body blue and then got the airbrush, lightly went over it, and went around the outline. Then I made the airbrush smaller and white and did individual dots along the back. For a little bit of a nicer touch, I added some sort of magical stone onto the string. I hope you like it!
