When I was a child, I heard a story about what happens to my friends' mom. When she was on her way home from grocery shopping by bicycle, a crow sit on the rear sheet of her bicycle and suddenly cried "croak, croak". She was so surprised to hear the voice from just behind her and had no idea how long the crow sit there. The story made me excite, and I expected a crow to sit on my bicycle whenever I rode on my bike. I was a weird kid.
There is a crow in the first sketch, but the composition was boring. And I put 3 more crows t and changed the story a little bit. Then, my roommate asked me " is this your trauma?".
I decide to give the title to this "trauma".
Since I graduated, I have been busy with many things. Finally I start working on illustration.
