no, its doesn't need a name on it... it doesn't need any text at all.. hell there's some people in this section that will tell you not to use text until you know EVERYTHING else...
comments: the lighting could be manipulated better.. it seems that the focus is on the background.. not sure if thats what you went for, but it would look better if the BG wasn't so bright, and if the render was sharpened.. it looks like the render you used is blurred, which would be great if you were going for depth on it, but that doesn't seem to be the case with this one..
Also it would be better if the sig was colored.. it's hard to get separate renders/stocks to match well.. such as a grassy background with a Halo soldier, you should adjust the Hue on the guy, so that you can match the color of the grassy background
