8 - Met the Challenge. I like this shot it is very clean and captures the 'feel' of the compass well. The colors are simple and there is no clashing and given the subject I do not think anything bolder is required as it would make the silver 'metal' of the compass 'fade'. Criticism; I would like to see even more sharpness on the compass, more emphasis somehow on it. Maybe a tighter crop taking out more of the top, but I realise you would then lose the rule there. Maybe turning that upside down to have the numbers and lines, as that would still fit in with the style/angles of the others. Perhaps more play on the shadow, not sure.
Good subject matter, good lighting nice shadow, however I would have preferred just one item in front of circle- perhaps on a 45 way over in the corner. Blue and green are conflicting and causing too much eye distraction. "8"
