This design truly surpasses the typical soft and dark contrast of pastel goth and punk; in doing the design stands as an example of what the style might achieve were it to broaden its conventions. The circular rainbow is typical of the style, but excluding the dark saturated blue and the black within the figure that is something else entirely, the rest of the colors break with the style in a subtle but significant way.
Typically to remain graphic in nature Pastel goth/punk images will bolster the design with outlines. Not only is that not present here, but the washes of the cape and scythe have been enhanced so as to create an oil on water effect that adds a toxic undertone to this effigy of death. The figure itself stands out in terms of value in a way that stamps it upon the more decorative elements of the piece.
What ultimately makes this image interesting is the use of value to create layers and varying weights within the image. The use of texture to create a hierarchy of interest and emotion. The wings as elements point to the greeks and Hermes, Seraphim, and (in their coloration) parrots. Pastel as an aesthetic is here challenged and expanded by light saturated washes. Pastel seeks to lighten the macabre through color, here it is made ethereal and pernicious through the masterful execution of shape and transitions.
