It is wonderful that her parents placed a higher value on joy, friendship, and teamwork, than on competition, and that this encouraged Daniela to pursue her dream, focusing more on sportsmanship than anything else. It would have been nice for Danela's mom to have shared an example of sportsmanship (through dialogue) with her from her volleyball days. It would have driven this home.
Your English translation needs some editing to remove mixed gender pronouns as Daniela changes between a male and a female throughout your story. You also shift between 1st and 3rd person a bit which can be distracting and confusing. Using an editor to check your piece for correct grammar and punctuation is therefore recommended. There is another issue that you should look to address and that is redundancy. If you reread the first four English paragraphs you will realise that your paragraphs repeat a lot of the same information from previous paragraphs and don't actually progress the story. You could lose your reader quickly if you continue to do this as it comes across as padding and no new interest is introduced from paragraph to paragraph. One final thing: make sure that you have the right voice when your characters speak. Lucia is described as six or seven years old but speaks with the voice of an older child and that can be disconcerting.
