More interesting, but why two figures? Loses emphasis, particularly since they're rather far apart, on opposite sides of the image. And while having the "wrong" shadow is intellectually jarring, having the intensity of the shadow vary so much between her feet and its "head", particularly with the distinct lower and upper halves, reduces the effectiveness of the illusion. Transparency is about right, IMO.
OTOH, if you hadn't have altered the shadow, having the same ghost ascending and descending - albeit perhaps a touch closer together - is an interesting idea.
And details - things like rotating the image to get the horizonal lines square to the frame, lining up the sidewalk stress relief "crack" to be square into and centered in the frame. I always forget to watch carefully during the passion of shooting, but slowing down - somebody's tag line includes something like "see what you shoot" - is important.
Lovely woman, lovely gown, and great location. Getting there.
Of course, you realize you're going to have to explain to us - well, at least, me, because I don't see how you're doing this so well - how you're doing this - in detail.
