Introduction for a Letter (CAE)

[Dilmunis]

Hi teachers! Today I have a task, but with a higher level, so I´m a bit lost.

Is this introduction well written (as you see, I have to complain...)

"I am writing with reference to an article which was published in your newspaper on the subject of the Brampton’s fifth Medieval Fair, desiring to express my disapproval of your opinion about it."

Well... "looking forward to your soon reply" hehehe, . Thank you very much, bye bye.

I'd take 'desiring' out, as it doesn't sound very natural. Then it would be OK. You could also remove 'about it' as it isn't necessary.
