Nice work Mark. 
If you haven’t already, consider registering (for free) on Sketchfab, you can upload your models and each is given a unique URL, if you then paste the URL into your posts here, the 3D viewer will be embedded which allows us to enjoy your model in all of its 3D glory (pan/zoom etc).
Just a thought and again, nice work
