Everything seems to have been given a great deal of attention, from the color of the subject's hair and her skin tone down to the shadows cast by her body and the ever-so-slight flare from her glowing eye (the one what's visible, that is). The pieces of armor have a nice design to them; compact and protective but sharp and intimidating.
Out of all this, I do see one thing that might be considered flaws. It has to do with the gold loop around her left upper leg (again, it's on the right to us); if her calf(?) is pressed up against it, as it appears to be, I'd think that the loop would create a small crease against it. I'm sure you've already put in quite a bit of work on this piece, but I hope this note helps in some way.
Other than that, I think this submission looks gorgeous, and I'm sure the alternate version will be just as appealing, if not more so (to some, anyway). Hats off to you on a job very well done, friend. I'm sure your commissioner will be quite pleased with the fruits of your labor.
