Default Cube (on a bad hair day)


low DOF

Not-so-low DOF


Grease pencil + wacom + cube + convert to curves in that T panel (no extrude, just bevel > depth 0.02, resolution 3) + some pbr material nodes, cracks node used to drive metal rougness = huge amount of geometry. Rendered with Cycles in about 25 minutes on some GPU.


And some test on more complex geometry
