3D Art Week 1 - Rendering Basic Shapes

I was working on these renders at home, and Maya crashed twice when the grayscale render was almost complete, each time after nearly 6 hours of rendering.  Luckily, the third time was indeed the charm, and the other images were able to render a lot faster (for some reason.)  I played around with modifying the Arnold preset textures for the 2nd and 3rd images, and I really like how they turned out!
