3d B Cardboard Reliefs

My 3D B classes are starting cardboard reliefs and they had to use 3-4 different types of texture along with layering to create depth. Since cardboard is cheap and easily found, the materials are easy to come by. They can elements of color to the projects or leave them natural.
Here are some examples of work that inspired them.
We also looked at the work of Mark Langan and Ali Golzad
