Really nice work, I've seen some pictures of it on the net and this oone resembles it closely!! I like the reflection and the triple holes
But, there are some things that need some touch up i think....
First the texture on the blade....it looks like there is alot of dirt on it now but it's grey....So i would make just a few scratches in the bump map and show the min your texture too, but not this big...
Second the relfection is great but if you're able too blur it, blur it!!
And third, the holes in the blad near the beginning are they cut out or texture?? Because at the time they look texture too me......
That was it i geuss
