It's fair for me to make a comment about how the look of the building could be improved upon. "Breaking rules" isn't a get out of jail free card, especially when the excuse is that the building is "meant to break all the rules".First of all, it doesn't look top heavy to me, but…
I don't understand how you can look at a design that is meant to 'break all the rules,' and then seriously declare 'well, it would work better if it followed this rule.' If it did, then it wouldn't be River City 3, it would be Yegger City 3, which breaks all rules except one chosen arbitrarily.
The deal with buildings of this nature is that they are meant to look like they shouldn't be the way they are, and removing the elements that provoke would only water them down. Take away the odd massing here and you remove a major element of what makes River City 3, River City 3.
