I don’t know the relation between a chess play and a bowling ball, but I like the dynamics of it. The camera blur increases this effect. Ending up in a nice composition. Well done 
Thank you. Original scene was a bit static, boring, so I came up with this idea of combining model from previous lections with chess set. Like one of the players was so upset that he/she had to use drastic measures, ending this nightmare of bad chess round. 
Now I see that it would be better if the pieces were maybe more mixed up, but this black/white polarizing composition also has some charm. Taking notes for future.
Kaiju,
This a fantastic render! I think that you did well with the textures and I like that the bowling ball is matte! There is a bit of an artifact on board where it is peeking through the edge. This is an easy fix with a bit of moving around. Cannot wait to see your future work.
