I started with 2 photo shots, taken from the backyard of the new apartment house, and stitched them together in Photoshop as you can see in the 3rd small image.
Later on, I got some fairly precise indication from the architect and was supposed to finish modeling, texturing/lighting and rendering...and...of course rematching the rendering into the picture with Photoshop within 2 days.
I hope I'll get some good comments and critics on this, due to improvements I could implement in future projects.
