It is however rather large (15x13 area-wise, and height wise I think it reaches nearly 7 tiles high at certain spots), so perhaps it's not the most practical custom model to use in a level. And I have to admit it looks mediocre, but sorry, that's basically how the model was originally.
There are 2 models, because in the original model, there's both a front and a side entrance to the castle town. So I made two orientations, one where the front entrance faces you (model1.3ds), and the other where the side entrance faces you (model2.3ds). For some unfathomable reason, despite only having rotated the model 90 degrees, the second model has much brighter hues than the first. Go figure.

The dead spot for both models have been set to where that well/pond thingie is. You'll have to play around and see where to lay out the X floors. It is a good idea to allow Stinky to enter the buildings, or at least to step into the entrance of the various buildings (and then maybe have a teleport whisk Stinky away or something).
If you really like the models but want to try out a smaller size, PM me and I'll look into it.
[EDIT: over the next few days I'll try to edit the colors so they are more consistent. The first model's colors are too dark and the second one's too bright, even though they come from the exact same original model]
