This character was sculpted and modeled using ZBrush and Maya. The majority of the hard surface modeling for the motorcycle was done inside of ZBrush, and later the topology was refined in Maya. Rendered in Marmoset Toolbag and editing/compositing of the image inside Photoshop.
The texturing work was done in Substance Painter, which allowed for fast experimentation and iteration. I was able to explore various designs and refine the textures without much of a hassle.
