Ok lighting's good, but I'd put some light source entities in there, to add realism, if you have money, you could get the latest update and use the in-built store to buy stuff, like custom characters and room segments, etc.......
Try and not use the stock media that comes with FPSC, youll find tonnes of good, (and free!) stuff on these boards if you search, it shows that you really went out and looked for stuff to enhance your game....
Finally, I'd add a bit more entities int your room, especially the first, and try to use some decals, they add greatly to the look of your game.....
An excellent start, I'd like to see this become a good game.....
