I saw a similar cube-like object in another gallery and thought it looked interesting so I decided to give it a whirl. It took about 15 seconds to model :-) and about an hour to experiment with materials and lighting. I modeled in TC 2017 and rendered with LightWorks Advanced Presentation 10m mode. It took about 15 minutes to render and about 30 minutes to save out at 2100 x 3750. Resized image is attached. I did do a significant amount of post render processing in Photoshop. I blurred the background and ground a bit and I adjusted levels and hue and saturation, otherwise it was a bit dull straight out of TC.
