Loek die tegen een muur praat en staat uiteleggen

"Loek, dressed in a casual blue shirt and khaki pants, stands at an angle facing a plain beige wall. With his left hand holding a small black marker, he's seen actively using it to construct a graph on the wall which he appears to be explaining. His deep-set eyes express intense engagement, while his mouth is slightly open as if caught mid-sentence. The nearby surroundings show a hint of a modern office environment with a whiteboard and a couple of office chairs in the background."
