They're absolutely not terrible shots if he just came out of the blue
But it maybe a good idea to have your aperture no smaller than 1/8 no matter what you're shooting unless you really need the smaller aperture for photographing stars, but for any other subject I'd look at the focal length before the aperture
like manntax said you run into problems if you go smaller, I think for aps-c f/11 is the absolute smallest aperture (not sure if focal length played a role here) beyond which the IQ degrades because of diffraction (the smallest details on your sensor grow larger than the pixel size, meaning you're not using all of the pixels and the pixels you do get don't necessarily have the right color/luminance because of diffraction)
