Last semester, we did illustrations of these models during our Midterm exams then we were made to draw them again after corrections were given and taught by our teacher how to shade.
So these are the output, the redrawn and shaded version. I finally had been able to start using the blending stump which gives more volume and texture to my works.
We also had to personally choose another two pieces to illustrate. This could lead us to mastery of the shading technique before proceeding to garment sketches.
