Yellow Submarine

Speed modelling video: https://youtu.be/nrdQEHMAEWo

It has nothing to do with The Beatles' Yellow Submarine. But the submarine design is the same with submarine in a game called Clonk Planet, or now the game is open source with name Open Clonk.
Originally was made in 2015 when i was very new to 3D modelling. Remake in 2018 with Blender 3D and textured with Substance Painter.
