it seems a little too thin?
either that or the images are vertically stretched or my eyes are just dumb
assuming it is to scale, and if its thinness is not in fact a product of image stretching or some crap going on in my eyes/brain, i'm assuming you took a 1x1x1 block to be a cube, when it is not and shouldn't be regarded as such when building to scale, as it is a little bit taller than a cube.
though i can understand that it'd be somewhat difficult to calculate the dimensions of the building taking into consideration the actual volume of a 1x1x1.
thinness aside very well done, loving the detail on the roof and at the street level, and i agree with daffytitanic on the usage of chrome on the base. the irl base does not seem as shiny nor does it look like several shiny tiles, looking at it from the picture provided, although this may be the result of interference from the environment that seems a little brighter than i'm used to
i'd give it a 9/10
