Great work and I loved the breakdown on your youtube channel.
Some tips for a better experience:
1. The field of view change when running is a bit too much and very jarring when you come to a sudden stop. Same with crouch height, maybe a bit too close to the ground.
2. Enabling TXAA might fix the shimmering caused on some objects.
3. Wall textures feel a bit low res up close, tessellation might make this less noticeable.
Fantastic job on everything else. The set dressing is top notch and overall feel is very close to an in game feel.
