Your chunks are not big. 🙂 If you’re getting gigs and people are happy then kudos to you.
Big plus for having a website and not using Fakebook.
I have a problem with this image, http://www.loribrownphotography.com/keyword/p1100305 Hate the cropping and to much junk in the background.
Regarding your equipment, your images would benefit from some better lenses and dialing the focus points. You would be better off finding a used D700 or spending a little more to get the new D600, The focusing is so much faster and much better low light performance that will let you get a way with cheap lenses.
