Two versions of an architectural rendering

These are 2 versions of a sample rendering that I did as part of a bid. I based the first version on high key, compressed value scale renderings provided as reference. It began looking too flat to me, so I added additional darks. The second version is closer to my concept of an architectural rendering and the lines were hidden to provide another option. The line drawing was done using the perspective ruler in Manga Studio EX and then colored in Photoshop, using some customized oval brushes that I labeled "UFO"s for brevity, although "almond"s would have been more accurate.
