The CV appears to be written correctly and the sentences are fluent and grammatically correct. However, there are some points that could be improved. Firstly, the "Professional Objective" section is missing and it may be useful to add it at the beginning of the CV to clarify your career objectives. Additionally, it may be helpful to highlight more prominently the responsibilities and achievements during your internship at the advertising agency. I recommend reviewing the structure of your CV to ensure that it is organized in a clear and coherent manner, and deleting any irrelevant or unhelpful experiences for the job you are seeking. Finally, remember to include the authorizations for the processing of personal data and to verify that all contact information is correct and up-to-date.
