A few issues:
1. Biggs Wedge Jessie.
Jessie's legs look too thin and stand out for the wrong reason. In fact, her new legs are awful and you can see how bad it looks when she is on the seat:

https://postimg.org/image/bmmcqszkf/I think her old legs were good enough - or pretty close, aside from the colour. The new colour is good.
Additionally, Biggs' old hair is correct and his new hair is not how it is in the art or originally.2. Colour issues. I think it's important to stick to the intended colours used in the game - regardless of any concept art. Look at the two pictures below:
Original:

3. Really not liking the new Cloud at all.
Old:

b. His hair is way too sharp now. Look at the older hair - it was nice and smooth and blended in. The new one looks like a razor blade. The original hair was fine.
c. The body to head proportion of the new Cloud is poorer than what you already had.
d. Why is the sword larger? Is this more correct - or less?
So I am definitely keeping the original one for The Reunion. The original one you made was more or less perfect.
4. Tifa: What has been changed?
5. Other issues for Reunion:
a. The half body version of Jessie is needed for Rootmap.
b. Updated versions of all chars (in Cloud's case the original one you made) that fixes the Temple of Ancients issue - and Experts' Hall issue (the 3 models there that are also transparent).
I will get back to you on Sephiroth.
Sephiroth seems to be unchanged appearance wise - and that's cool because I think he's perfect as is
The transparency fix seems to have worked.
