I like the direction you took there with the manipulation effects to the stock Sir'. It really shows you are trying new and different ideas with effects and overall composition. Even though the colors are fair and in between; I would have to say the 2nd original with the added light source is best in my opinion. It also is the only one that comes close to having any depth. The black and white one would be decent with some appropriate high lighting. The other ones you posted later on just too dark and over contrasted. They really tend to appear messy up top in the VERY bright spot there. But the effects used like around the arm/elbow look sweet. Keep it up man...
