This is a 3D ink piece I sketched in a virtual reality app called ANIMVR.
I used an Oculus Rift VR headset.
Theme was inspired by the Inktober challenge.

I found it fascinating to be able to concept in 3d space using VR headset and controllers: https://vimeo.com/256302585/bb2980e8d3
I continued with many projects after this one adding kit-bashing, sculpting, shading and rendering in my process. The video is captured directly in the ANIMVR app, no shading or rendering in another 3D package.
