Very nice camo and weathering, great overall effect. As mentioned, some of the smaller details could use some work, but the only thing that irks me is the line where the muzzle breaks are glued together.
Looks good. Camo on minatures is always a problem. If you do them like they are ment to be you end up with something that distrects so much you cant actually appreciate the model. Do it badly or less prominent and it doesnt feel like a camo but like some random painting. yours is some where inbetween. A slightly higher contrast might have been better. The magnatising is awesome. seen a lot doing it very badly but yours seems flawless. Oh and like others said weathering and those details are good looking, but the chain look to new, i think.
