NEED HELP WITH MY LETTER OF MOTIVATION FOR AN LL.M.!

Hello, this is my first post here. I am composing a letter of motivation to be sent in to one of the Dutch universities (in order to apply for a Master's) and would like someone (preferably native speakers from the UK) to proofread and edit it lexically and grammatically. I've looked through older threads and realised it's a common practice to ask for assistance in such things, but in my case I don't use English as the first language (my native one is Russian). In addition, this is an intimidating task to prepare a strong letter of motivation as I did it rarely before.
If there's someone who can give me a helping hand, I'll post a first draft here.
Thanks in advance!

Cheers,
Faust.
