I wanted to do something surreal for my composition involving a disembodied head so Magritte's paintings came to mind:
Reversal of objects and figures was interesting but I wanted to see how I could add more of a story so removed the apple. Also considered a lab setting and did a thumbnail sketch of that.
Someone said a human head wasn't enough of an object so I changed it to a skull and now thought it looked more gothic so thumbnailed a castle interior. This inspired me to look at Harry Clarke and go for a similar dark aesthetic.
Thumbnails also considering value and line of sight. The bottom thumbnail on the second page is strongest in terms of line of sight and use of value to create contrast:
The reverse of values in the shirt and background and trousers and floor is also effective in making the figure stand out more.
