The sniper (yes, he is a Ratling) looks pretty good. Bit more depth on the skin with a wash or two and tidy up his foot.
The rifle - can see whta you\'re trying to achieve with the Matte black scheme but does need something to bring it up a bit - extreme edge highlighting should work here.
However, my main suggestion would be to improve the base - the black/grey stones and grass don\'t look right together. I would overbrush the stones with shades of brown and drybrush the grass too. This would compliment the camo scheme better too.
For a first posting, you show a lot of promise (nice colour choices, neat brushwork and excellent work on the camo) and we expect great things from you now... welcome:beer:
