Got currious and looked into the metadata on our pictures. You are using 1/30 of a second in shutter time combined with flash and a low iso value..
1/30 should be more like 1/150 to make a more stabile picture, increaseing the ISO could make that possible. But the best is probably to take the pictures in more bright light without the use of flash. Btw. your focus distance is set to 7.3mm (a little under three inches), anything from there and out should be ok.
Will let someone else comment your Lugers, I 'wasted' enough working time for the day
