Okay, my review on the pack, I'm gonna repeat some of the stuff that shell said, but-
Models wise-
1. Ironsights are not the same as they should be. For example the SCAR's rear ironsight is a flip down
Diopter sight, and the G3(and other weapons based off of it) rear sights are
drum sights.
2. When you animate, you need to time it correctly. The animations almost seem robotic, and if you want to get a smoother transition, then you need to make sure that there's a certain amount of time between each transition, so when you play it back, it looks normal.
3. The models are a bit too thin. They need to be able to fill the blockheads hand more or less, and that bevel around the gun if there is one could look something like the picture attached to my post.
4. Barrels on some of these guns could use 5, 6, 8 sides, and if you go above that, try to use smoothshading in conjunction with smoothgroups, which will then look like a curved flatshade. When you do it right, it looks really nice.
5. Despite the other stuff up there, you've actually improved a small bit, so I'm hoping to see some major improvement after this.
