Nice modeling and rendering, Eddy. About the glass, that texture looks great when there's a sky backdrop that matches it, as it appears like the sky is reflected in the windows. It almost works in the first image, but thee sky has fewer clouds and is lighter than the glass image. In the courtyard view, one would expect to see the opposite walls reflected inthe windows, so seeing the sky insttead looks odd. You might try a dark gray glass, adjusting the transparency, and then setting it's reflectancy in Podium. You miht also want to find a new grass texture - that pale green doesn't look natural.
