Here are two from the jpg using gThumb curve, then adding Uniform+curve+saturation. In the original, I originally saw the overpass as the side of a building next to the muraled ones, which need masking.

Never used gThumb as an image editing tool. Thanks for the tip.
Not sure where this will appear. I think Jean-Marc_Dignejmdigne’s fresco and my second underpass might show the most detail, if combined.

@lightlover Looking at your elaboration I begin to doubt my initial choices. Perhaps there was really no need to ensure that the areas in light and the shaded areas had a similar exposure. I really like your version, I feel it mine, if you understand what I mean.
No shadows, no party.!
I think that if you open the shadows too much, the result is a flat Image. Maybe nice colors in isolation, but overall too flat.
