I don't find this shot to be fitting of the "Dave Hill" style of processing. Maternity shots should be soft to the touch and elegant... Not harshly lit and grungy. There's no need to accentuate the discoloration in her stomach due to her pregnancy.
Frankly, if my girlfriend had a maternity shoot with another photographer (other than myself), and it came back with this type of processing, I'd be offended.
That's my opinion though.
