As I have suggested to others I think shots like this needs some human interaction to introduce some feeling into the scene, otherwise it just looks static.
the more that i look at this photo, the more i like it. it could be a little sharper, but the colors and lighting are good. i also like the angle at which you took this picture - much more appealing than a "straight-on" shot.
Moving the center of focus off center might have helped the compositon flow a little better. I think it was a good choice to focus on the lower left like you did.
I think Risk used to be one of my favorite board games... I like this photo! It brings back memories of a time when I had more time to play :) The only thing I *don't* like about this photo is seeing the edge of the board in the botton right corner. A little tighter crop on this photo may have helped the overall impact. That dark spot is just a minor flaw that attracts my eye to the corner of the photo.
