they looking good, for I have a couple of sewers areas in my game  on two different worlds, and they would be perfect for that.   You done a good job in doing the basic shape of the sewer tunnels, Only thing they need now is some bricks inserts on the sides of the tunnels or grooves, to give the tunnels more 3d depth once you are inside the tunnels..

Are you going to maka piece of sewer tunnel that also slopes the tunnel uphill or downhill?  This would allow us to create a 3d sewer system with more than one level of tunnels...  Yes a longer tunnel piece does needs to be made.

I think Most people think in Linear terms from getting from point a to point b, when it comes to making tunnels and stuff, and that's probably why it didn't cross your mind at the time to make Corner pipes with diagonal pipes for walking upward or down levels of the sewer system as well, but when I write a game, I like making games that are multi-dimensional as I'm doing a space sci fi combat story line driven rpg game and looking for models that will suit the game. Why?  Because I'm not a 3d modeler so if any 3d modeler wants to makes stuff for my game they will be credited.  because of the type of game I'm making, a big large space game that covers many different worlds, I have got a hell of alot of stuff to try to find to construct the worlds in, have to build the interior of the space ship as well as make all the different worlds. That's why I come on here looking for assets that I can use.  Currently looking for a space pilot chair at the moment because the file I have one in which I got from a free modeling web site was in the old *. MAX format and blender dosen't even have a MAX plugin to import unfortunately, it only has the newer 3ds plugin instead for importing 3ds studio max files. so I couldn't import it into blender and then export it into fbx for unreal to use it as a result because I don't have 3ds studio max or maya. just blender.

Do you know anything about Unreal Engine UDK?, I been trying to get my models in unreal editor to do stuff, but they are stuck in their defaut t-poses at the moment because I don't know how to animate them....Because I'm not doing the random spawn bots, but using imported custom models. but you have to set up a custom pawn script for them somehow and this I don't know how to do and when I look at the tutorials on you tube, they are all about changing your main player custom pawn script or scripting spawn bots...  And because of this, this is alot more harder than I thought just to try to animate these 3d models once you import them into the unreal editor. So I'm stuck on that....

Do you know the 3d cat that shows up on the Blender Splash Screen a while back I think it was ver 2.3?  Fishy Cat its known as. Well the author of that model has allowed me to use the cat in my game, which I decided to use it as an alien pet on Telos and decided to call it a Leonix.  (The game I'm scripting up is known as Tesseract Prime Offworlds the Unknown Universe, it has no relation at all to the Telos planet that exists in the star wars universe but this Telos is part of the tesseract prime universe so its a completly different world.).....  My game does not contain the star wars universe in it. 

This cat will has cloaking abilities, and you can buy it as a pet for your ship but the only problem is the cat has only had just the head and neck mesh modeled for rendering in the blender splash scene, the body mesh hadn't even been modeled yet, so I also need to try to find the rest of the body for it so the cat can be rigged to walk around in the game on my space ship.  

I work on sewers for a living, so I've been very tempted to create something like this.  Maybe I'll expand on this set some day... but don't hold me to it. ;)

I have a million rats in one sewer in my game, the sewer network is huge, encompasses undereath all the city.  many tunnels, easy to get lost in
