Yes those pictures of trenches really showed all those non-believers it is possible But seriously, good to see some progress. A bit of constructive criticsm on the skins, increase contrast a little to define pockets and stuff and maybee sharpen but not so much as to distort the colours. The British tommy soldier is a bit too green and you need to make the camo a bit more noticable, try using the levels and colour balance to make it more visible (if you are using photoshop)

Good luck with it
