perfect! roman: watashi wa(ha) nihongo no benkyou ga suki desu。 hiragana: わたしは　にほんごの　べんきょうが　すきです。 hiragana+kanji: 私は　日本語の　勉強が　好きです。 You can also use "ha" instead of "wa" after "watashi"; we pronounce "ha" as "wa" only when it comes after the subject marker. (Grammatically "ha" is correct. Verbally "wa" is correct)
