Hey that rifle looks fantastic man, you did a great job on it, very detailed

As for that other rifle, I'm really looking forward to seeing the re-texture, along with the pistol of course too (although I must say I'm still gathering reference photos, and sorry they won't be side views (I can see how that would be beneficial however), but so far I'm simply collecting "in-game" photo's, just to sort of give you some ideas and concepts of handguns to draw some inspiration from).
As well, I'm looking forward to that segment pack if you do choose to make it, also excited to play the demo for sure; it will be fun to be able to explore your environments.
Oh, and if you are looking for some critique on your RPK, the only thing I could think of was, again, the texture. It kind of looks as if the black parts of the weapon (the majority), are covered in oil the way they shimmer. I think it would really compliment your weapons to have more dull, dirty, but still high-res and good quality textures.
Keep it up man.
Cheers
Life would be much easier if I had the source code.
