This is a 3D paper structure. I used the technique of making volume from planes to build sphere-like structures by stacking pieces of circle cardboard together. I used smaller pieces to the bigger pieces before going back to the smaller pieces. I also used analogous colours of dark to light blue to create a cool feeling.

My artwork is my self-portrait. It is drawn using pencils. Using the method of smooth blending with different tones,  To draw the face,  I shaded the shadows and made parts with highlights or reflections lighter. I also used dark and light, thin and thick strokes to create texture for the hair to look more realistic.
