Miyuki and Yumi - what are you staring at (Patreon)

A quick update. 

Amber Illustration is nearly finished but since I have to color it, it goes like: . . . just the shades and highlights and some gradients and - long story short I try to make it as good as possible and that takes way longer than finishing a sketch.

And since I promised sketches for some of the other entries here is the Miyuki one.

Background: Miyuki is a high school teacher who suffered an unfortunate accident (or two) while Yumi is her pupil fascinated by her helpless teacher.

Miyuki soon realized Yumi's interest (Yumi by no means a saint was suddenly collecting detention as if it was trading cards) and the two enter a complicated relationship. 

By now Yumi just stays after school is over pretending to do her homework.
