This was made from the highest-resolution image of the original poster I could find on the internet (at the time).
I think it was a little bit under 1920*1080 so I DCNN-upscaled it 200% to scale it back down to 1920*1080.
On the original poster the road is white, but I challenged myself to turn in to black.
The process consisted in cutting Kaneda and the motorbike out, tuning the color-curves of the background,
and adding the reflections back on the windshield.
That's right, the shaded white road with black lines became a plain black road with black lines.
The reflections are the only other thing edited here. Everything is possible with the color curves
