Eindhoven, The Netherlands. For over a century, Eindhoven has been the place where light has been the main source of income for a lot of inhabitants, who worked in the light bulb factories and laboratories.

I used Procreate for the sketch, then I moved to Affinity Designer for vector work. I constructed everything from scratch.

And of course the final result and a close up of some details.
