how to make an image more crisp

• At the bottom left, the "black point" has been move to the left to coincide with the most values you have in the image (the darkest tones aren't black in your image). This increases (slightly...) the available range.
  
• Increasing contrast is done by using an S-shaped curve with a steeper increase in the tones where the detail is. The Contrast bit of Brightness-Constrast does it too, bu the steep increase is around 128 and this isn't always where the details are.
  

Done with 2.10 (which is why there is a split view) but you can do the same thing in 2.8 (without the split view).

Well done.
My different approach, just to try:
- duplicate layer
- add a mask on this duplicated layer white to black (top-down)
- set this layer mode to multiply
- new layer from visible (normal)
- duplicate visible
- unsharp mask
- set this layer to multiply (75.0 opacity)
- duplicate, desaturate, invert values, set to softlight (25.0 opacity)
- final layer as new from visible
- apply level to have the lowest value to pure black
