Because of the bright background, your image took a bit more processing than I normally use (Processing steps below image).
Post Processing Paint Shop Pro X
1) Duplicate Layer [this step helps to balance the light a little bit]
- Desaturate duplicate layer with Hue/Saturation/Lightness
- Change to negative image (Menu location Image/Negative Image)
- Set Blend Mode of layer to Overlay
- Set Opacity of layer to 50%
- Merge layer to background
2) Double Unsharp Mask Action
- USM [radius 50 - strength 15 - clip 3]
- USM [radius 0.3 - strength 300 - clip 3]
3) Duplicate Layer
- Desaturate duplicate layer with Hue/Saturation/Lightness
- Set Blend Mode of layer to Soft Light
- Set Opacity of layer to 50%
- Merge layer to background
(Steps 2 & 3 are from Benjikan
Benjamin Kanarek post processing method | PentaxLife )
4) Clarify Action @ +2
5) High Pass Sharpen @ [radius 2 - strength 90 - blend mode: overlay
6) New Adjustment Layer - Curves [as shown below]
