I personally think your statement is still a bit formal, and doesn't really get down to the core of who you are. I disagree with Evil Muffin; I think you should leave the playstation bit in. I don't think the statement is going to make or break your application though, since I'm sure grades and references are more important for study abroad. Plus, they will probably take into account that you are an international student when reading your statement, and that as a UK student you are taught a completely different format for writing personal statements. I'm sure the majority of international students write the statement like yours, so I wouldn't worry too much. Above all, make sure you are comfortable with what you are writing.
I guess it's kind of hard for someone from abroad to really understand how we Americans are taught to write admission essays. In the US, we are encouraged to have a glowing essay that's super creative and original. It's so different from an essay for UCAS. Though some students still write really serious yet moving pieces and others that aren't quite as skilled at writing write really dull cliche essays, a lot of American students write really amusing essays that would be considered too "fluffy" for British admissions. The following is an essay that was given to me to help me write my college (university, to you British folk) essay. Though I would never be quite so risky with my essay, it's interesting to note that in the US, this would be considered an acceptable personal statement. (The applicant was accepted at NYU).
I am a dynamic figure, often seen scaling walls and crushing ice. I have been known to remodel train stations on my lunch breaks, making them more efficient in the area of heat retention. I translate ethnic slurs for Cuban refugees, I write award-winning operas, I manage time efficiently. Occasionally, I tread water for three days in a row.
I woo women with my sensuous and godlike trombone playing, I can pilot bicycles up severe inclines with unflagging speed, and I cook Thirty-Minute Brownies in twenty minutes. I am an expert in stucco, a veteran in love, and an outlaw in Peru.
Using only a hoe and a large glass of water, I once single-handedly defended a small village in the Amazon Basin from a horde of ferocious army ants. I play bluegrass cello, I was scouted by the Mets, I am the subject of numerous documentaries. When I'm bored, I build large suspension bridges in my yard. I enjoy urban hang gliding. On Wednesdays, after school, I repair electrical appliances free of charge.
I am an abstract artist, a concrete analyst, and a ruthless bookie. Critics worldwide swoon over my original line of corduroy evening wear. I don't perspire. I am a private citizen, yet I receive fan mail. I have been caller number nine and have won the weekend passes. Last summer, I toured New Jersey with a traveling centrifugal-force demonstration. I bat .400. My deft floral arrangements have earned me fame in international botany circles. Children trust me.
I can hurl tennis rackets at small moving objects with deadly accuracy. I once read Paradise Lost, Moby Dick, and David Copperfield in one day and still had time to refurbish an entire dining room that evening. I know the exact location of every food item in the supermarket. I have performed several covert operations for the CIA. I sleep once a week; when I do sleep, I sleep in a chair. While on vacation in Canada, I successfully negotiated with a group of terrorists who had seized a small bakery. The laws of physics do not apply to me.
I balance, I weave, I dodge, I frolic, and my bills are all paid. On weekends, to let off steam, I participate in full-contact origami. Years ago, I discovered the meaning of life but forgot to write it down. I have made extraordinary four course meals using only a mouli and a toaster oven. I breed prizewinning clams. I have won bullfights in San Juan, cliff-diving competitions in Sri Lanka, and spelling bees at the Kremlin. I have played Hamlet, I have performed open-heart surgery, and I have spoken with Elvis.
But I have not yet gone to college.
