the kanji on the second line reads "Kokatsu" which could mean "crafty" or "sly" by itself but in this situation the word is used to compliment the drawing.

Coming in a bit late, but I looked up usage of the word, and I didn't see any examples where it was used as a compliment without meaning "crafty" or "sly". How does one derive that meaning? (Also, there was another line of commentary, possibly added after you transcribed it here.)
