It's been some time since I've worked on something just for the sheer fun of it. To explain isometric shapes in class and how someone can use the 3D feature in Adobe Illustrator. To do that i started with a simple sketch on a piece of of paper and then I've added the details. Playing with colors gave me 2 different options on this design, 1 brighter and 1 blueish. 

There is still place to work on this design but this is the initial one.
