Looks good, but here's my problems:
1. First screenshot, near the blood there is a weird shadow. Im pretty sure it's because you have you Lighting Shadows = Best for performance, but you might want to fix that for the final game
2. Second screenshot, the textures are really weird in the doorway, there may not be a way around this but you might want to fix it..
3. Additional screenshot, Whaaa? It seems really random, it looks like a war game now. Going from a scary apartment to a very lit up snowy outside map. Maybe lower the lighting so you can't see as much. Also make sure the crosshairs go away when zooming into ironsights.
All of the above is just my thoughts, if you want to fix my recommendations go for it! If not, then don't! It's not my game, so i can't make it how i want it...
But that's my feedback and i hope that it helps, Good Luck!
EDIT - Sorry didn't mean to be so rude, as this is your first game. It looks good though and i hope you add some more screenshots!
