Yesterday I finished my recent model, a medium detail version of the Oriental Pearl Tower in Shanghai. Currently the complete texturing is missing, that's why actually it looks really CG like. Here's a bottom to top zoom:
A very useful tutorial I used is this parfum bottle tutorial from BlenderNewbies. It teaches you how to effectively use Blender's array, simple deform (blend mode) and shrinkwrap modifier. The only change I made was that I used on the simple deform (blend mode) the value of "2*pi" which gives you an exact complete 360° circle.
