Looks like I can't edit the OP any more, so I'll post the latest right here!
Here's a shot of the low poly with normal and ambient occlusion maps, the same with wireframe overlay, and the beginnings of a diffuse texture!
The wires show that quite a few parts aren't as optimised as they could be, but I see this as probably being a pretty important part of a game environment, the player might even ride on it at some point, so I think the detail is necessary.
Normal and AO map need some manual fixing, and the diffuse is going to need a lot of love, but I'm excited to get this finished and looking great!
I'm loving this thing so much.
