Computer Art assignment

One of my first art assignments has been in my class "Visual Form and Communication." Right now, we're focusing on using the building blocks of visual communication to send a message. In order to practice this, we were told to pick one major abstract theme. From this theme, we were to pick three sub-themes. For each sub-theme, we would create four representations. One theme all in points, one all in straight lines, and one using only curves. Then, recreate two drawings from each category digitally. Here's mine (my overall theme is "unintentional beauty"):

My Sketches

Curves- Grand beauty

Points- Minuscule beauty

Lines- Man Made Beauty
