Beautifully done!! You really took advantage of the props and the soup looks delicious!!! (I just ate but now I'm hungry again....)
P.S. That white miso box is also the one I like to get! It's so mild
I can't help but want to contribute some miso soup cultural trivia:

You can also use dashi/Japanese soup stock instead of plain boiling water.

In authentic Japanese inns, Miso soup is generally served at the end of a multi-course meal, not as an appetizer like in America.

No one serves miso soup with udon noodle spoons in Japan....

In Maison Ikkoku, the hero tries to propose by saying "I want to eat your miso soup" (i.e. come cook for me)... as I recall he is totally misunderstood, and winds up getting miso soup.

Pouring miso soup on rice tastes nice but used to be looked down upon as a really low class thing to do.... (But they do go well together ... just keep them separate!)

People allergic to shellfish or iodine should not drink restaurant or commercial miso soup because of the seaweed content (someone I know learned this the hard way)!

I had one more but can't remember it....
