Some nice looking screenies you got there, I has Returned.
Evaluation:
Screenshot 1: Nice case model with a Uzi inside, but I noticed there doesn't appear to be lighting?
Screenshot 2: The restroom comes off as way too big, and the Urinal looks a bit strange placed like that. Also, the switch inbetween the two sinks really doesn't fit in with the whole toilet scene.
Screenshot 3: Not very interesting, simply the dirty toilet from Model Pack #2.
Screenshot 4: Nice idea putting a ladder into your game, but still it all seems a bit boring. Try adding some thing on the wall perhaps or you put in lighting and make the top of the ladder dark, and you can see juuust the outline of an enemy up there.
Screenshot 5: Just a corridor with a door, an enemy and the camera from Model Pack #2. Sure, it looks alright, but still a bit boring.
Screenshot 6: The room looks too large, a bit more than the restroom, but I liked the effect with the blood on the walls and floor, however it was a bit overdone.
Screenshot 7: My response is the same as with Screenshot 6.
Overall, these screenshots give a nice feel for the game, but you really, really, really should add in lighting. Lighrting can make or break a game. Good luck with the game,
Tom
