Are they disco zombies from the 80's or something? lol perhaps you want to tone that colouring down a bit, its quite bright. Also consider making them look torn or dirty, but of course its up to you. And with the police car, just keep trying and use keep that reference image glued to your face.
Another thing I've noticed is that the skybox is visible on several pictures throughout you're thread. Seeing the skybox really breaks the atmosphere, its never like that in real life. I bet if the player jumped next to some of those walls they could see over and into the skybox. This is an element of game design that absolutely must be covered.
Consider fixing that by:
-
Placing objects outside of the playable area
-Never have the skybox visible with only 1 segments height difference (ie, higher fences)
-Or (actually definitely), only having the skybox visible above the tops of buildings. This is plausible for the city environment.
-having a dark/night skybox, its far less noticeable and any light inside your playable area is much more attracted to.
The most important point is the first. I've selected a random picture, and edited to show where buildings (or extra detail) should be. Please note that there are many more I could do the exact same thing for.
What this does is:
-Adds realism
-Adds immersion (comes with realism)
-Adds detail
-Doesn't make the player feel so restricted
Its a hard thing to make the player feel free in an FPSC outdoor environment, and well done for the exterior environments you've created so far. However just by adding detail beyond the playable area you chip away at a much better game.
I've included another image as an example, but I've attached it to the post as to not spam you're thread. Here I've whipped together a scene that includes four buildings (could be done with three). Here's two screenshots to highlight my point. One is in the editor, so show how bare it can be, and one is in game, the view of the player (most important). As you can tell it's night, but that's just because I couldn't be bothered changes around my settings. With few building's I've created the impression there's more to this place than you will ever see, and that's a subtle but important detail. In a city environment, there's always something next door, always! The concept of that screenshot could be taken and applied to your levels.
It's not too difficult either, simply placing more buildings that conveniently block the view of the skybox does the trick.
Now I'm no expert for FPSC, but these little tips will help you (hopefully) take your game a step up to the next level.
Keep up the good work, hopefully you can look at what I say positively as its honest constructive criticism, I hope I'm not being too harsh.
Few, long post.
