All the characters have similar facial features because the physical aspect of the humans and angels are more idealized and not individualized. The figures are not meant to look like specific individual people. The style of the hair is also quite idealized; the angels have long wavy hair and the souls have short hair. None of the human souls have organs to help differentiate whether they are male or female. This could be a form of symbolism which shows that there are no genders in Heaven. This could be implying that all human souls are no longer differentiated by sexual organs and everyone is the same. The angels have a multitude of different colored robes and wings, such as subtle reds, blues, and greens.
