Ghost Train Design

I have now completed the basic designs for the project that I need to start modelling. I have a basic layout of the track which states what needs to be in what areas. I have a drawings of possible (not final) cars for the ride and the front graphic design and also block/untextured drawings of characters/props seen inside the ride, so I know how to model them and will try to texture in most of the details rather than modelling to save polys. The monsters are more detailed as these are my own designs so I need reference for when I model and texture, they will use more polys as well as you will see the monsters a lot more close up compared to other models.
