As per the title.. a skateboard! I modelled the geo in Maya several years ago for another project, and re-did the materials and textures now as an exercise to get more familiar with Substance Painter. Rendered in Arnold. The grip tape texture is 'Skateboard' by fedebruno94 on Substance Share, https://share.allegorithmic.com/libraries/3402 (NB that material includes wood also but I utilized the grip tape part only). For the deck artwork, I used a cheeky cartoony self-portrait that I did a few years ago.
