I like the DOF you have used and the choice of white blocks at the back/top makes the ube fade nicely into the background. Contrary to some comments I'd say this was a good fit for the challenge - what a way to fill in those hours of boredom! My only gripe would be the reflection in the blue tile on the top row.
nice shot, mine is in my trash can with the stickers peeled off ;) i think that a slightly greater DOF would have worked better because the bottom row is quite soft on the sides.....8
Games, puzzles and the like are interesting to me. I recall a cousin of mine spending hours fascinated playing with his Rubix cube. So, for me, the subject is not a good fit for the challenge.
The photo itself has interest, however, The limited DOF, the play of colors, the subtle reflections work well. I think perhaps a square crop could add even more as there seems to be no good reason for the extra white space on either side.
Lighting appears a bit "top down" - good shadows at the bottom, but the colours are maybe a little subdued on the sides. Good photo though, and a nice idea for the challenge. "Bored" (or maybe frustration) might have been better coveyed by a Rubik's cube with the labels picked off, but that would have been less aesthetically pleasing (and would have ruined your toy).
