All of the images above were taken with the 18-70mm kit lens. I have a SB-800 flash that I used in commander mode, but you don't have to do that. I use it so I can adjust the angle of the light on the fly. Try using your flash, the flash on the D70 will sync at up to 1/500sec, so set your exposure mode to M(anual), try an exposure of about 1/320 sec @ f/5.6, adjust your shutter speed until the histogram has data across the entire exposure spectrum.
