Very interesting, how large was the file that you ended up with? Did you consider doing something like re-topologizing the model to refine the results?

The final .obj file was about 100Mb. I actually did get around to retopologizing the windmill, however the amount of holes present and the errors on the blades of the windmill pretty much ruined it's practicality. Here's a render of the retopologized result.
