Hi Jared, I think this is a lovely portrait and I'm sure they are ecstatic!
My only nit is that there are a couple of hot spots on their faces from the key light that I find distracting; specifically on her forehead, cheek and chin and on his cheek. Easy to correct in post w/ a clone brush, set to darken, and low opacity.
Otherwise, I think it's great and you did really well with the fill and hair light. Nice work, my friend!
