YSLBagLVR your translation is great

You understood everyhing correctly.
She's not famous here in Brazil, but after the cover, things may change.
Here's the full translation:
"The girl from Juiz de Fora, Minas Gerais, Havne Jacob (
what a weird name haha) was the great winner of the cultural contest
Quero Ser Capa da Elle (I Want to Be the Cover of Elle), sponsored by Rexona Women, that reunited 2761 candidates from all over the country.
Havne didn't believe she would go that far: "I already was shocked when I knew I was among the finalists. I almost couldn't speak. Imagine the emotion to be cover of Elle!
Model for almost two years, the beautiful girl with long and brown hair already spent three months at South Korea, but she tells she went back to Brazil because she missed her family. Last year, she started to study nursing, but she decided to delay her plans to invest again in her model career.
Havne reveals to the magazine that it's even more difficult to find nice works in Brazil than in other countries: "Because of that, I believe that being cover of Elle will open a lot of doors to me".
The rest is about the magazine, not her, so I didn't translate.
