The shot is well framed with the chips, but seems a bit hazy. I think even running this through the quick automatic adjustments in photoshop would help to take away the yellowish cast and brighten the whole shot a bit.
I like the photo, it feels like it's lightened too much a bit, because it feels like there's a fog over it, or the colors are muted or something...but, that could be my monitor too I suppose :D Good frame though!
I did a similar idea to this in my submission, and although I think this is a little flat in contrast, I like it much more than my own picture, its a great subject idea for the challenge. Good luck :-)
I really like this shot. It's well composed and does a great job of conveying the feeling of a poker match. On the technical side however, it seems like the white balance is a bit on the yellow side (at least on my monitor) which is a little distracting. All in all it's a really good shot though.
