reflecting on my first critique

the critique i got was that i should add more color and more lines to my drawing, but almost everyone in my group got what was drawing was supposed to show(which was people watching war happening and not doing anything about it). it felt fine to get critique from my classmates because they were very conscious about how they critiqued my drawing and were sure not to be mean about it, but they still gave me critique that i could use to improve my drawing with.
