I am looking for someone with architectural 2D rendering experience for a small job. I want to visualize a pedestrian tunnel from both sides of the tunnel.
The tunnel goes under train tracks. On one side of the tracks, a long alley provides room to build a sloping walkway so that, by the time the walkway has reached the tracks, it is deep enough to start the tunnel under the tracks. The distance available for the incline is about 40 m. Bonus points if you can show concepts of public art along the walls of the incline.
On the other side of the tracks, the tracks are elevated about 15 ft above the sidewalk, so the tunnel will just emerge from below the tracks right at street level.
I have sketched up rough versions of the idea in paint to give a visual of what I'm talking about. I'd like you to draw in convincing-looking tunnel entrances.
