Once base color and main values are layed out, it is time to work on rendering and figure out final lighting. 

Still a ton of work ahead but quite happy with the shapes :)

Now working on the placement of different elements and drawing basic shapes. At this stage I am also trying to figure out more storytelling within the main narrative.

It is getting ready to start with shading, throwing in some values and details.

After some brainstorming, I came up with a couple of ideas for the story, involving a precious brain-shaped element within a decadent atmosphere. I would like to depict the contrast between a doomed environment and the rich, prosperous and creative inner human mind.

I have decided to use a central composition to really draw attention to the key element, thanks to some thumbnailing and value studies. Additionally, I have done some facial expression sketching to capture the outer mood and the shape of the key element
