Am I correct in assuming that the first render in the series is from a different proposal to those following it?
Stylistically it is quite different from the others; plus, the final render in the series appears to be from the same viewpoint.
Assuming this to be the case, they each have their merits. Of the second proposal, it is good to see big, bold, architectural statements being proposed for such a central location - the last render is indeed startling.
For all of that, my aesthetic preference is for the design depicted in the first render. But both are impressive.
It's nice to get a good render after months and months of nothing, eh?
