First time I've seen this post, and my gosh, I am impressed!! You did a helluva job! I really enjoyed your creativity! The camo looks great!
Sorry about the not being accepted, but keep on troopin' in this outfit!! It's awesome!!
A couple suggestions if I may?
I really like your weathering, what I try to do, is weather the helmet w/ scratches, rubs, etc. as if it's been tossed casually into a bulkhead compartment. Little nicks and the like.
On the camo, a different color of "dirt" and grime weathered in it. As a sniper, you're going to be crawling alot, up and down, perhaps more extreme weathering on your knees and shins.
Shoulders- you've had to tuck in close to rocks for cover, a bit more off-colored overall grime, different colors of metal showing, some metal wear is more recent than others.
Your black vest, I really like the look of it better than the brown, but it needs some weathering too. You might try misting it w/ dark grey spray paint, and a couple lighter shades as well.
Another good weathering technigue is earthtone chalks. Shave them into powder, apply w/ your finger until you get the look you like, then hit it w/ a matte sealer.
I really like your armor concept, a bit more "aging weather" to enhance the veteran mando sniper and it would rock even harder than it does!!
What about some kill marks? Perhaps on the rifle, or left shoulder armor?
An outstanding outfit!! I want to see more of it!!
