Dear Sir/Madam
I hope this message finds you well.
I am currently working on a project for school, and I would like to kindly request permission to use your game assets as part of my work.
The assets would significantly enhance the quality of my project, and I assure you they will be used solely for educational purposes. If needed, I can provide additional details about the project or adhere to any terms or conditions you might have.
Thank you for your time and understanding. I look forward to your response.
