This probably belongs in the critique forum.
I'm assuming you shot through an open window with the engine off. Shooting through glass or with the engine running can cost you detail. Auto glass is awful.
The light you are shooting in does not provide much direction. That suggests detail is hard to render.
I'd edit with selection layers in LR Classic.
You can darken the background by 1-1.5 stops. I'd increase saturation and drop Luminance of the Blue channel in the HSL panel.
For the subject, you can increase Clarity to give it more contrast, and increase Texture to bring out some feather detail. It looks sharp.
If you really want to push feather texture, you can use Topaz - probably Photo AI would be my starting point. Don't add sharpening, NR, texture or clarity before going to Topaz if you are using an edited version. Also try with a Raw file as a first step, and then finish the edits in LR after Topaz.
Any noise reduction comes at the expense of subject detail, so use noise reduction lightly in all the editors.
Next time, before I use ISO 7200, I'd drop the aperture and shoot wide open rather than f/8. You could have picked up a full stop and reduced ISO to 3600 or 3200 at f/5.6. That would have provided more detail because Noise Reduction could be lower. I think the exposure is fine with the Exposure Comp selected.
