Thank you for all your fantastic work! I'm blown away by the effort you've put into this project and I'm excited to see how your work can help my organization and me.
With your team's solution in particular, I approached {{aspect_that_could_be_improved}} the same way when I was getting started. Since then I've learned to {{general_tip_trick_or_question_you_wanted_to_see}}. This is a good practice for most projects in my industry and I hope you'll be able to apply it in your future!
That aside, the way you've {{process_that_led_to_aspect_you_like}} impresses me. Your work here shows in {{aspect_of_solution_you_like}}, which will be really valuable for {{how_you_could_use_aspect}}.
Once again, I'm so thankful to have been a part of your project and glad I got to see what you came up with. I work on projects like this all the time, so if any of you felt like you found your calling or want to learn more about my work, I'd be happy to talk more about it with you. Your teachers have my email and phone number, so please get in touch!
