This is a scene that I made for a 3D art contest held in the Blender community server. The theme for May 2019 was "Arctic Machine" and this is what I made in accordance to the given theme. It took me about 2 weeks to make it, though I didn't work on it as my main project and only worked on it in my free time.
I also made a video breaking down this scene. If you're interested, you can check it out here:- https://youtu.be/cbjB1_3th8k
