Environments look nice, however your story isn't really the pinnacle of originality.
Oh, a few historical inaccuracies:
The M4A1 you're using (in the first few screenshots) is innacurate, as it wasn't introduced until 1994, and you can't really pass it off as a Colt Commando as it looks entirely different. The handgun you're using is an M92, which again is historically inaccurate because it wans't introduced until 1975.
Regardless, your environments look really nice.
I just now realized I've had a typo in my signature for the past 3 years.
