A little underexposed but the shot tells a great story - I can see it very clearly. Did you experiment with more extreme angles ... something shot more from a long angle on the table might have been more compelling.
Some creative lighting would have helped this and setting up the shot on a croupiers table or adding in a dimly lit smoky gambling den surroundings with cigarette ands and half drunk whiskey glasses etc etc. It's just abit flat and dull as it stands
Great choice for a habit. As the picture is I think the lighting could be a little better. To really stress the habit, I may have added the human element by having just the hands of someone holding the fanned cards in from the bottom, to give the sense that someone was looking into the cards. There is a lot of white in this shot, I might have staged this on woodgrained table/desk just to add a little more color. Add a cigar and a few beers (this is a boys in the kitchen setting) and you would have have many habits in one. Good shot though, just seems a little staged without the human element to me.
