Letter of Motivation - please help

Hey guys,

since my english isn't the best i would realy appreciate it, if someone could check my letter of motivation for grammatic errors.

here it is:

I am writing to apply for the Master program because I want to continue working experimental in the field of digital media, broaden my horizon and improve my skills in various areas. During my studies I was able to pick up complex knowledge of design fundamentals for different types of media like film, web and print which is necessary to implement more complex projects.
I focused on extending my knowledge in designing and programming websites in frontend and backend development, particularly because I had the chance to do a few commercial projects in this field. I think the knowledge of webdesign is a good basis for many other projects like the _______ which I’m developing right now within the scope of my bachelor thesis. It’s basically a digital signage project with the aim to make the ________ virtually walkable and to provide information about upcoming events and student projects – you can already see a beta version of the ______ on the big screen in front of the_____. However, I will stay interested in various topics and do a wide variety of projects because I don’t want to be stuck in one particular field of digital media. During the Master-studies I want to experiment and research with the abilities that I have acquired in the Bachelor program and, of course, improve these skills.
I want to find useful and aesthetic solutions for complex problems, which I haven’t researched yet and I’m convinced studying is the best time for doing that.
Besides I want to develop concepts and ideas considering the most recent technological developments and look beyond the horizon.
I firmly believe that it makes me a more competent developer of digital media if this time of studying, researching and experimenting is given to me.
I want to continue studying at the __________ because here I always felt comfortable and privileged. The atmosphere is very nice, classes aren’t crowded and the competent lecturers provide a high variety of courses with a focus on the design of digital media. The study course Digital Media is pretty unique and I really like the interaction between designing, programming and sometimes even crafting.
Over the years I have learned to appreciate the __________ and during my semester abroad at the ___________ I have seen how studying is at another university. The experiences which I have gathered while studying at the ___________ were nice and instructive, but I always felt stifled in my creativity, because the system is more like school and not as free as in the _____________.
Last, but not least, I want to stay in ________ because my social connections are here and through my second passion beside the development of digital media – the design of facades and event support through graffiti - I have already built up a local client base.

thank you & regards!
