the things you should consider in any personal statement are: why exactly are you applying to that masters? you can give a number of reasons: first and foremost you enjoy the topic, but you will also need to explain how undertaking this course is somehow going to enhance your career prospects in the field you are interested in
secondly you need to consider, why should they take you onto the course? certian masters courses can be competative so you may need to make your application stand out. emphasise your academic achievments relevent to this masters: high grades in particular subjects or coursework assignments, relevant industrial experience and so forth
thirdly why pick that particular univeristy? you could probably do the same course at hundreds of other institutions. best thing to say here is that you have picked Warick in partulcar becauce of its outstanding reputation as a leading educational institution.... anything that appeals to the vanity of the univeristy.
