I don't really like the blocko-style. But otherwise they are quite good. Some models seem to be a bit too big. The Magnum is shooting cannonballs, not bullets. The military sniper is a instant hit weapon and shoots a bullet? What?
THIS explains what I mean.
You advertise with custom animations.
...Every gun (minus a few exceptions) reloads, with custom animations...
THIS is a custom animation. Or do you mean with "a few exceptions" all weapons?
Make custom animations, don't make some hand movements. Custom animations or no animations. Not something in between. And the hand movements when shooting look... interesting.
But all in all, this pack is okay.
