I painted this creepy scientist lair as part of a school project, and had lot of fun learning more about environement painting ! Here's the process
Here you can see the final render of the Mad Scientist Lab I realised as an environment design project.
Here is the basic and final sketch of the room, showcasing the furnitures and details i'd later paint in the chamber.
On this picture, I added some highlights I'd use later as my landmarks for the lighting all around the room
Finally, here you can notice the solid colours I applied everywhere to give me some more marks as to what the final product will feature. The final colours are already here and the details without further painting are showcased.
