How do you say your French is beautiful in French?

In French:

"belle" feminine

"beau" masculine (or "bel" if in front of a a Word with a vowel sound at the beginning)

"belles" feminine plural

"beaux" masculine plural

example: "Fresh Prince of Bel Air"...That's the name of the area or neighborhood the guy is from. "Air" is a masculine French noun and begins with a vowel so you must spell beautiful as "Bel". It means "beautiful appearance" or a place that is said to "look beautiful" in French.

Also, some of these adjectives have been turned into English Words. For example, the Word "beau" is commonly used to refer to a boyfriend in English or as a popular first name for a man. Belle is used in saying such as a "southern belle"...like a beautiful, well mannered woman back in the old days.
