I didn't really get to try the sniper, it flew out of my hands.
The dragon flamer thing just seems like a normal flamer, the flamer bullets also pile up.
The shotgun is very fun, I like how it works.
The soldier seemed okay, but the whole person is too dark, so I cant really see the details.

And there's a little terrain rape problem with the machine gun. And I agree on using a lighter color on the soldier.

Hrmmm...I don't really know how I could lighten the solider up, he uses every shade of grey there is. And don't worry about details with him, he doesn't really have small details.

That's a bad thing.
I'm sure there are more shades of grey.
brb.

I agree with whoever it was who mentioned AAL. The colour scheme looks like a bit of a rip-off, but that's your choice anyway. I personally would like to see the Orange highlights done in green.
