I am seriously thinking about dropping out of college and trying to make a living drawing random people on the street. I know I sound like a hipster, but it is a childhood dream come true. In order to do that, I took some pictures of acquaintances and worked on portraits of each one of them, they all praised and said it was perfect, but they might as well be lying just for the sake of the friendship.
I'm here to ask you what you think.
