Visual Book - AI 2

I started doing my visual book by using AI again. I changed my illustration style, so that the drawing could be more roughly.

Here were what I did :

I tried to draw the black dog in every scene to represent the main character always feel depress. And the last scene, I would like convey a message "Maybe the others will feel depress as well. However, they just act to be happy. " Therefore, I draw the black dog on the every car. And this scene could also represent traffic jam, just like what I experienced before. I would like to related the story to what I saw before, so I tried to include the traffic jam scene in my visual book.
