Heh, this was probably about 5 hours including the paper sketch it was based on. :/
I'll get much faster with practice though , the goal is 1 - 2 hours so that it becomes more efficient to do a few renders like these than actually building the model and do real renders. Normally the workflow in the design world is probably rough sketches -> detailed sketches/2D renders -> 3D renders. Whereas my workflow has the 3D modelling quite early.
The last step might be a (real) clay model in scale 1:8. We'll see if I actually get to that point with this project or if that will have to wait a bit. We have the clay and tools at uni, it's just that it takes a huuuuuge amount of time to get it right.
