Dissection of a Digital Illustration

Photoshop – of course

Everything ends up in Photoshop sooner or later. The insets, which were created separately, were integrated here, and the arrows added.

And 3D renders usually need some touch up. It's much quicker to do some of that in Photoshop, rather than try to get the render perfect. Here is the final composited render, before Photoshop.
