I've done a lot of portrait photography and am nitpicky for sure.
This is GREAT! They're expressions are in synch, pose is excellent, her hand and his hand are well done. (so many photographers do not pay attention to the hands) And just the right amount of fill light for their eyes.
Only thing I would suggest is to tone down that little spot of wall showing between them.
Philip, this is just a wonderful Portrait, I like everything about it, lighting, pose, tones and colors, very well done and keep up the good work, Regards my friend, Cheers,
