Fully agree with Jerry and tao..
long grass does not look like that!! Check it out on the real thing (or photos of). My first thought was splashes from bullet impacts!!
Kurt might have a point as well! A tree or at least a bush would add to the 3rd dimension. A fold in the terrain could maybe help.
I am also missing the number one on the MG!! It could not be the guy with the SMG, and the other bloke with the binoculars does not qualify either.
There are strict regulations about wearing helmets in various situations and duties.
Finally the camo looks a tad dark and does not display typical patterns (splinter f.ex.).
Apart from the above, there is something about this little scene I like very much!! Maybe it is the consistency in the colour palette..!?
I see talent!! Well done...but get rid of that grass!
Cheers
