Japanese flower sushi

Thanks to Eslite bookstore, TLC Channel and my good old times back in Australia.
Because the nutrient I acquired from them, I get to appreciate exotic food and foreign cultures.
This dish is my own version of Japanese mixed sushi.
It's only prepared for special celebration such as graduation, great success in exam, good luck with new job, etc.
I prepared it for a picnic held earlier in March back in Tainan.
We had a great time and a big laugh!
