An interesting idea. I love globes so I am drawn to this entry. I think lighting could be more even but then again the dark shadows provide a little more drama.
Pretty picture, but unfortunately, the hightlight on the globe is blown out pretty dramatically. This is, granted, incredibly picky... it seems that the back of the hand is every-so-slightly soft: this can be improved in 2 ways -- smaller apeture or position the camera further away and use zoom.
Nice technical quality! The only thing I would point out that there is a difference between "power" and "strength". Power is a more generic term, while strength is a word describing physical attributes such as raw strength and longevity. (you are by no means the only one. Check out this thread: kamps.org/g/?vkmv) I think you picture describes "power", but not "strength", and hence falls outside of the challenge. Sorry. (2)
