Much better color than the first, better crop, nicer image overall but I still don't like the hand position very much, it's the years of traveling with a portrait studio and watching them set up shots. But still an improvement. Your original got a 6 from me, this one gets a 9, would have been 10 if not for those hands! :)
The hands should IMO be in same position (looks better) as they did but it is good to see the chair now.
The model - is it the same? Maybe younger sister or daughter?
The eyes look much better in this photograph. More colour in them.
Also the expression is more "sophisticated" then before.
Your wife's gaze is mesmerizing my friend. The positioning of the pinkie is slightly distracting but I think this is a better improvement than the first one. She seems more relaxed and comfortable in this shot. Great job!
