The trooper

So i got a camera....now i have to learn how to use it!The top three photos so far.I'm not sure what I'm doing right or wrong.Input would be great.( if any one is even looking)

The first pic is of a rank and file member of the 48th skull head div.Cloked in the MK 4 field jacket with A.P.D. rapid response camouflage dzine.The 2nd pic is of one of my lutenist's....also in the mk 4 field jacket  but his is adorned with the Fall of nuheillfield winter camo.Very rare indeed.
