I can understand what you mean with handmade craft and things made nowadays with modern technology. Every craftsman puts his thoughts, his passion in his work and even having irregularity makes such stuff unique. I still have some of old jewellery from my mother and she got from hers, they were handmade in the past and they are so impressive, although made if silver decorated with unknown stone. But they are so precious for me just seeing such an old work.

The temple's roof is a bit different it has such sharp angles and not going down in a smooth curve, does it mean something too?

Seeing dragon's sculpture it is obvious that they are important feature of Buddhism as much attention was paid to their decorations :)
