Really impressed by this photo. Love the focus and the close-up. Pity about the dark top left and bottom right, but realise it would have been impossible to avoid. Voted a 9.
Nice execution of the macro shot. I'd have liked to see more of the keyboard, possibly a perspective shot showing some other keys. But very well done, good lighting/shadow work.
Nice composition, but a bit too much lighting. I'd like to see a more even tone on the top of the key. Kudos for somposing so well though - the diaganol orientation is great!
