I'm not really an expert on macro photography. I'm pretty lazy when I take photos during battle reports myself. I think your photos are looking a lot better over all and a little shake and blurr can add to the feel of the battle. I don't know what kind of camera you have but I'm guessing it's some kind of point and shoot. These camers often have a shutter delay which can cause blurr. The shutter doesn't actually fire when you press the button on a lot of point and shoot type digital cameras and cell phones. You need to make sure you keep holding the camera still for a second after you press the shutter.
A small tripod could help out a lot. Also you can check you camera manual to figure out how to control your focus.
Not trying to dog on you. I really enjoy your reports!
