looking at her website and comparing the before and after results, I would suggest you might like to try this in Lightroom. Get the image density right, the original examples on Krissy Allori site in general seem a bit light. . Then crush the blacks slightly using the dark slider in Lightroom. You'll be surprised the effect that gives. I'd then add some vibrance, or saturation , whichever gives the best result, and then add a vignette. Finally evaluate and make any small changes to give the result you want.
