Recommendation Letter for Interactive Media / Games.

The expressions are too plain and colloquial... And there might be some grammar mistakes. Please help me. Thx!

To Whom It May Concern,
xxx is an exceptional young lady. I am pleased to recommend her for the Master's program at University of xxx. I have been her supervisor for one year, during which time I witnessed her tremendous growth and development. I know she would do well if given the opportunity to continue her education.

To begin with, xxx is an extremely intelligent and insightful student. In the project of xxx, she has proven her strong self-learning ability and collaboration spirit. She quickly learned and mastered new programming languages such as JavaScript and PHP all by herself with her extensive previous experience in programming. Finally xxx completed the APP XXX in four months with another student majoring in Industrial Design, which also showed her excellent communication skills and her gift in interaction design.

Besides, xxx has always been keen on game design. She participated a game project in our lab and donated her summer vacation time to that and the study of Unity 3D. With such curiosity and desire to learn and make games, she is energetic and concentrated all the time. She also made some indie games, which are popular among students. I appreciate the efforts she put into each game and project because she would continuously share her enthusiasm and her progress with it, which made her an outstanding student in this direction.

It is for these reasons that I offer high recommendations for xxx without reservation. I am sure her potential and abilities will continue to grow in your program. Thank you for the opportunity of correspondence.

I edited the post to give it a tighter and more informative feel. Let's see if it will work well for you :-)

Having worked with XXX over the past year as her supervisor, I am privileged to recommend her for acceptance into your institution. She is an exceptional young lady whose self learning ability and collaborative spirit works well with her extreme intelligence and insightfulness.

Her ability to learn intricate programs and languages such as Javascript and PHP within a few months, mastering them within a year, has helped to highlight her natural interaction design gift as a student of Industrial Design. Her curiosity and desire to learn how to design games caused her to recently donate her summer vacation towards learning Unity 3D. Working with other students, she proved to have a communicative and collaborative soul that places the completion of the project above any personal ambitions she may have vested in the project.

It is because of my believe in her ability to redefine the videogaming industry as we know it that I highly recommend that she be considered for a student slot at your university during the upcoming term. I am sure her potential and abilities will continue to grow in your program.
