Congratulations on your graduation and on your GPA. Relevant work experience can certainly enhance your application to top universities such as the ones you mention. Focus on acquiring legal experience in a law firm, corporate legal department, NGO, or judicial internship. Strong recommendations and a compelling personal statement highlighting your achievements and professional experiences will go a long way.
