Good focus, lighting okay, but I feel that maybe you could have loosened the crop to leave the top of the knuckles, you have left good proportion at the botom of the frame so IMO maybe the same at the top.
Maybe just slightly tilted to the right...small rotation anti-clockwise required.
Overall a good compostion = 5 as is
Good shot! Minor, minor note- the hand looks a bit tense, which adds to the feeling of it being a set up. Turning it towards the camera slightly, or relaxing the back fingers a bit might help.
Very nice, the white background sets this all up nicely. Very clear and lots of detail. Great shot. Being nit picky in a commercial sense (no points off here) the angle in which the hand is placing the coin makes the index finger appear a little puffy and unnatural near the knuckle . This would be a good stock photo. Great job.
Nice lighting, nice composition, nice subject. I know this is hard but it lacks 'zap', don't know why though. Feels like one of those 'stock' photos used in financial magazines - no bad thing ;-)
a very good quality picture. Right in the challenge theme. I just wonder what would the picture look like without the hand, or the hand without the watch. still a good vote from me.
