I went to a firework festival last week with my wife.

Japanese are fond of fireworks.

I like their sound when they are go off because it is resembles the sound of a Japanese drum.

Simple error, phonetically, it might have sounded like a "b" instead of a "v".

Because you use the word "like," this means you currently like, so the word "gone" should be "go" to show that the action in the sentence matches the time tense of your "like".

When writing, imagine your words as you are speaking. Because if you were speaking, you would pause before the word because, you show write a comma ( , ) to tell the reader to pause when reading.

Resembled was changes to resembles, because just like you presently "like" the sound, it presently "resembles" the sound of a Japanese drum.
