I think half of the work is over: lighting, shaders and details satisfy me.
I do not give more importance to the pure 3D part or to the post production, both workflows are according to the final result: create an artistically effective image that satisfies the customer.
For the following project, taking into consideration the fact of presenting only one point of view, I chose to create a good base (nothing technically extreme) and then to rely on photoshop for the inclusion of an important factor of the initial concept: the univeritary students.
The inclusion of people into the images helps to contextualize the environment and give a more human and emotional factor to the final work.
