Wow! Love your work! Sorry there are no shows for you to take part in.
You are such a great artist
There are many International cake shows. England, Italy, Germany to name a few. Found a list on line by Ruth Rickey. But you could google individual countries as well, especially neighbouring countries. Hope this list may help. Your work is definitely good enough to exhibit.
Sorry you couldn’t participate in these International Cake Shows. You have tremendous talent and I’m sure your work would have yielded some Gold awards!
