Scene I started working on during my free time in the summer, returned to it recently to finish & polish it with feedback from classmates.
Created & rendered in Blender 2.93 and textures done in Substance Painter - finished render is 800,202 tris.
The topology near the bottom right edge of the map, and on the rim of the ashtray isn't ideal, but I personally felt it didn't matter as this was created for the sole purpose of being a cool rendered scene.
Smoke from the coffee and cigar are simple planes with alpha diffuse maps - and hidden in the wireframe view to show concealed geometry behind.
