Really nice ... especially love the 'virtual window tint', I use that a lot too, not too difficult in PhotoShop but the result looks great.
I have to agree. The windows are the one spot where many images fail. I hate it when someone just cuts out the windows. (background) Adding glass back in as in this image where the glass is tinted or clear glass where there is just a light shading makes the difference between a poorly done or properly done rework.
