How to write a good thank you letter to my manager? - thank you letter to hair stylist

The performance of my crib I sent a letter of thanks, said he had some comments of things on my performance. I wish him a letter of thanks for my attention and I will always work as hard as ever, and I will do my best not to disappoint them.
Well, as you see, it's so obvious that I am not the words of an official letter. Can you help me? Thank you in advance.
