Lighting is key to photography. The only difference with that one from the other entries is it used a different type of light source than the other entries. Which personally works since rapper/MC = night club and the lighting gave it a nice night club feel. As for as being the "only" thing. Click on the picture to check the details.
Good eye by the way on spotting the color of arm change from black to gray on naugem's dwarf. I hadn't noticed that.
From past experience it’s pretty easy to miss a rule by accident and get DQ’d. I don't think they did it on purpose (elf and dwarf). I’ve had to re-read contests posts up to 8 times before finally posting an entry to make sure I that caught every detail of the contest.
