wait.... that's kinda rushed out... did you read it all??!?
here's my opinion, take it or leave it, but from one writer to another, criticizm is the basis of living...
I like how you gave him this "perfect" life with his rich problems... which is basically all the frat guys in my college... but it's not believable... not one of us i believe really fit into the upper 1% of society that he envelopes. His girlfriend seems to be the party type, but give more background on them... 400 dollars on a dress? how long had they been dating... how many birthdays have they had? was he planning on marring her or was it just to pass the time? You say he loves her, but make it known from her perspective on how she feels, to even the playing field... it's too one sided..
the race was nice, short but sweet... the detail on the engine was nice, but also put into the matter his heartbeat was racing as well, because you make it seem like while he raced, he didn't feel anything.. and when you don't feel when your racing.... your fucking crazy.
build on it... give the charactors more features, and it seems like it'll become a good story.. i'd personally like to know how it ends.
