Is there a special thread or some place where folks upload their complete .blend files? It could be very interesting to see how various artists manage their work, as well as their Blender layout. One single good file can hold more value than dozens of tutorials altogether.
Search for “free blender files”.
But that dont replace a good tutorial. In the resulting file you dont see in which way the result is archived.
And you may see a “way” but could not reproduce it until you find all the needed settings to do so.
You could try blendswap.
You can download the demo file for every Blender splash:
I guess if you study each one of these by heart you’ll gain a lot.
