I like both versions. The taller version separates the base from the tower, which is interesting, but the shorter one seems taller, because it rises up from the sidewalk uninterrupted. It looks as if the developer prefers the shorter version and is looking in this direction, even if it takes a few years to find a single tenant.
One more view for fun. I usually don't post the perspective views.
Thank you again to everyone for the nice comments.
