Can anyone help me to choose a unique design concept for my wedding?

Hello everyone,
In the last week of January, we celebrated my sister's wedding.
Her wedding was unique and memorable. After having meetings with different vendors, we finally chose a banquet hall in Vaughan
Her wedding day was not only a success, but all our guests were left happy. The food was delicious, the cake was amazing, flowers were beyond anything we had expected, and the service was perfect.
Since the day I got engaged, first I decided to book that banquet hall. There are only six months for my marriage. Now I'm a little bit confused about choosing a concept to design my wedding.
Can anyone help me to choose a unique design concept for my wedding?
