1. First problem was when I used plaster for the face, at first I couldn’t stick the plaster very well so it took so much time to stick the first layer of the plaster and then next day I tried so hard to stick the plaster and then I sticked the plaster very well it took much less time to stick the plaster.
  2. Second problem was when I paint the face with pink and blue the color was a bit darker than I thought so, I changed my plan to color the shape first and then stick it to the mask.
