Definite vs Indefinite

In this image I included the rule of emphasis, definite vs. indefinite. I created a square with a appealing blue color and made a line through that box with the same color just a lower hardness an opacity. I also included a dot on the top right of the square with a slightly higher opacity than the line. I believe I was succesful in this because I made the square really appealing, which was the goal. The square is what i see at first glance.
