Pixels or Atoms ?

As a break from real cars projects, I tried a few weeks ago to model some Lego assemblies. Here are some of the pictures I produced :

These pictures show the progress from page 1 to 11 of the book for the model #8448. I found scan for this model on a wonderful site about this topic : http://www.hccamsterdam.nl/brickfactory/theme/index.htm (see in Technic #3)

Here is the topic I opened on SMCars.net to show model avancement.

I will post a short Howto to explain the way I did it, if anyone is interested.
