After doing three thumbnail sketches of all different angles, I decided to make my final on the close up of the balconies.
I didn't add as many details as I wanted to to my final sketch. From doing this sketch, however, I finalized the angles for the building and the placement of the windows, balconies and other components that make up the building.
Today, I started adding values. I know the windows are going to be the darkest shade on the final piece so I started adding the very dark values. After doing the darkest parts of the windows, I started adding values to the bottom of the building.
