Catering to strengths. help?

I'm 16 years and female.

(Sometimes I wish I had a male range but that's a hopeless wish >.<)

I'm planning to enter a solo competition for Latin.

I don't know how to go about picking a song.

I'd like to avoid anything too common.

I've decided the best way to go about this is to cater a song to my own voice but being as uncultured as I am, I don't have any Idea what Latin songs would really suit my voice. If I really needed to, I suppose I could compose somthing, but I nearly always get caried away in the instrumentation and couldn't possible limit myself to one voice with a limited range and a piano. So I'd like to avoid a certain trauma I would experience by such limitation.

Help please? I would really appreciate it :sweat:

This might help

Last time I checked,

Singing Range: Bb4-G5

Extended Range: D3-Eb6

Tessitura: D4-D5

Other info:

I do not have much natural vibrato, but there is some.

I suppose to compensate, my register changes aren't very noticeable.

I'm rather good with technically chalenging things as far music goes.

Differentiating between notes in fast slurs isn't a problem for me.

that's all I can think of right not. Any help is greatly apreciated. :)
