The helicopter isn`t so far away, so it must be bigger,
The flag..The post of the flag is all over white,you could make it darker from the right side cuz the light source is from left.
what did you do with the soldier? Smudge it a lil?
N same thing with tho soldier, you could flip it, so he would look to the left, then it would be perfect, cuz the light is from left.
