That's really rather good, Camo on the cloak is excellent. The colours for the scout in general look good, muted but nice. If I may, perhaps the cables for the rifle could be a contrasting colour (though tactically speaking your choices are spot on - BRIGHT cables in a warzone = bullet magnet). Also, the little skulls on his arms could perhaps be lighter, just to give the figure some more 'pop'.
I can't make out what the basing material is but it compliments nicely. If you have some dead grass that would really accentuate the camo! The base rim - I always file mine a little with a needle file to get rid of flash and casting marks. This one looks like it could use just a few touch ups. I like the the rim colour!
Warbringers are fun - I've seen a few around here before... Hmm... Food for thought
