However the class was a scam... the tutor was so bad that I, at that time, can even draw better. The content was also only about those "anime proportion", nothing helpful at all. The schoolwork was also becoming heavy at the same time and I didn't have much energy to attend more classes, so, although this is a bit silly, this is where I started to self-learn.
