I was thinking about how to properly show Kartze’s emotions, they must represent emotions, which I would like to show in character, as accurately as possible. So I decided to make sketches of his emotions for a long time and at the moments when I personally experience really emotional periods of my life. Actually, next to the sketches, there are also small notes about what I was experiencing at this moment when this sketch was made and in what situation I get  this emotions. And later I'll be able to analyze the sketches and say exactly whether I could convey what I wanted or not. (Personally, it seems to me that I was able to correctly display such a hot-tempered person and his emotions in this experiment)
