Hello! I've been trying out your project and it is great!
I'm testing it for the first day, and here's a couple of things I listed:
Bugs:
Character bolt_ons don't disappear when the player is dismembered;
Weapon bolt_ons don't follow the main model animations (e.g.: M203 and M4, AK74 and hands);
No muzzle flash;
Some map objects can't be hit with the knife (e.g.: vending machines, boards, paintings).
Suggestions:
Widescreen support for 3D (currently, you have to set, for example, "r_customheight" to 1080, "r_customwidth" to 1920, "r_mode" to -1 and then "cg_fov" to 100) and 2D (no workarounds for these yet) elements;
Set first person weapons and hands as dynamic objects, so they react better to lightning, making good use of specular and normal maps.
