Thanks @Bluemoon5 and @Torcello
My (frequently changing with software updates) post processing now begins with an Akvis (Sketch, Draw, or OilPaint-abstracted) layer(s) blended with the original photo (Often HDR).
I then duplicate the blended layer and go to Topaz Studio where I sometimes begin with the Adjust Plug-in but almost always begin with a FineArt preset. Usually modify some of the components like Basic or Edges or etc.
Sometimes I treat the first studio visit as background, then return to PSCC and duplicate the original image and select a "central" subject that I use to create a feathered layer that I return to Studio with to modify with the same basic presets adjusted so the detail of the central subject is a little more photorealistic than the background.
I generally flatten the image and finish with Exposure X2 for a subtle vignette.
The key first step for you, I think, is to adjust your image in TS, LR or PS so the histogram covers the subject (clarity works well for this) then explore the presets in Topaz Studio until you find one or two you like, then experiment.
