I used ofnuts 'Luminosity Masks' plugin from Ofnuts. You can find some information about this here : https://www.gimp-forum.net/Thread-ofn-luminosity-masks
Once installed, you find the plugin here in the gimp menu : Script-Fu / Create New / Luminosity Masks
The plugin create a few layers with different masks according to the brightness in the photo. On this layers you can manipulate different regions on the photo with gimp tools. I used the 'Colours / Levels' and the 'Colours Curves' to darkenadd more color and contrast on the LLL and DDD layers. To darken the manipulated LLL layer, I copied this layer a few times with screen mode 'Multiply' and copied the DDD layer with layer mode 'Screen' and set 20% opacity on this new layer.

After:
And a little saturation (Colours / Saturation)
