Dedicated method of enumerating above minipages

I want to enumerate a set of tikzpictures with the label being above and in the center of each picture. I would like to do it with an enumerate environment and not to have to insert each label manually.

The first set of pictures is what I do manually and the second set is a not-so-good enumeration.

MWE:
