The juxtaposition of the two hands of cards really makes this one, you've really got an image within an image here. On the one hand, it's the visual center is The Card Game, right there very strong very definite. Then you've got a framing picture around it, of two men, looking at their cards and both apparently pondering the hand, so the outer picture is of two men playing a game. Then finally the whole thing is placed in a kind of interesting context, which is just out of focus enough to avoid being too distracting (the strength of the inner image helps here) but not so out of focus as to be abstracted away.
The eye dives in to the center, and then surfaces, and is nicely captured by the framing elements. There's a whole little story here (albeit a simple one -- Bob and Dave played cards) and that's nice.
As a formal composition, I can't really tell if it's "good" or "bad" because the human, touchable, elements are so strongly placed.
