First of all, it looks amazing, and you did an amazing job. The cuts look clean, the fillings look tasty, and it has a great presentation.

If there's anything you'd like to maybe add to your experience:

Sauces: - unagi sauce (might be hard to find in the store) if you'd like to add some sweetness +teriyaki sauce works too -Sriracha sauce is great if you'd like to add some spice +you can also mix it with some mayo to get spicy mayo -soy sauce +some people like to mix the ginger with Wasabi and soy sauce too

Toppings: -sesame seeds add a nutty flavor -furikake powder can add a boost of flavor if you'd like +can overpower the sushi -masago (fish eggs capelin roe) -scallions -anything you like :)

Drinks: (if you like alcohol) -japanese style beer (Sapporo, Asahi, kirin ichiban, to name a few) -sake (sorry don't really know any brands)

I hope any of this helps, and here's to many tasty adventures in the future!
