Welcome to PSG, PWilliam.
I agree with Mr. Tom that to make any sort of reasonable judgement about the work of a wedding photographer, one really needs to see some of the expected pix, eg, B&G, posed group shots, etc..
That being said, the one comment I can make is that unless it was your intention to do so, there is too much of an HDR / exaggerated local contrast look to the boy.
It's your call, of course, but FWIW, I'm not a fan of color efx (ie, your sepia toned look), either. My feeling is that such "styles" will become very dated in just a few years (...sort of like the way we now regard bell-bottoms and Afro haircuts from the 60's and 70's or disco clothing, pants suits, etc. from later years), and the B&G will eventually wish they had more conventional, color-accurate / straightforward documentation of this important day in their lives.
OTOH, "styles" are a very personal thing, so, you have to go with what you feel comfortable with, and what you think will please the B&G.
Cheers,
Tom M
