I'd say sticking to English, Italian, French, or German would show off a Western-style voice better. While it's good you won an award and whatnot, you need to keep in mind that you must play to your strengths. English and European languages that are typically taught in voice study are taught for a reason. The vowel sounds are more open, the accent and pronunciation leads to better overall vocal technique, and the sound itself is more pleasing to American ears.

While I've always thought it was a shame that I can't realistically mix my two greatest loves, like I said, you need to play to your strengths. Common vocal repertoire became that way because it does just that, and while it's not terribly unique, it's really helpful as a teaching tool and performance study.
