Brilliant phrasing and your descriptions create clear images in the mind of the reader. Only suggestion I would make is perhaps you're trying to use too many devices with the repetition of 'the agony' and 'precision', as it perhaps detracts from the main plot, although I can see what you're trying to achieve by doing so. It's a great piece of writing.

it sucks

ur good, but those annoying words will make the reader bored.

also, work on plot devlopment.

u'd be good in the future, and'll have a lot of fans, just not me. ;)
