Jewelry animation EEVEE super fast render, less than 4 minutes

play with EEVEE again today, seems quite interesting.
Totally 160 frames, takes about 4 minutes( i forget to count):stuck_out_tongue:
Do you think this is usable in real work?(i am an engineer , i don’t know what your CGer actually doing during work):D:D
what do you think?
