You should look at some other military / war images - see some of Mario Minichiello's large war /reportage drawings. Your work will get interesting when it moves away from being a replica or a static representation. There needs to be comment or a point of view. This could lead to some interesting juxtapositions. Look back to Goya and some of the early caricaturists like Thoamas Rowlandson etc. What you are trying to say - is the important question to ask.
