I wonder if you got the patient back in and shot some 100mm macro shots if you could show the scarring?
Actually, the ultimate B&A shot would be a video in high def on a DSLR camera with a 35-105 zoom then you could show the "portrait" and the "close up" and the video is really 24 high def pictures a second. Set up a better studio/lighting/lens setup maybe?
I also wonder if centering the donor site on the spine rather than off to the right would produce a more natural result long term? The asymmetry seems like if there was scarring you'd be able to notice it much more easily...
