"Create a set of 3D icons with a uniform design system that represents 'Delete', 'Complete', and 'Error'. The icons should feature a slight glassmorphism effect with smooth, rounded edges. Use light purple and light pink as the primary color scheme, ensuring a cohesive and modern aesthetic. The 'Delete' icon could be a trash can, the 'Complete' icon a checkmark, and the 'Error' icon an exclamation mark. All icons should have a soft, glowing effect, fitting within a cohesive and minimalistic design language."
