Here's a video showing some of the steps and tips for assembling the Smaug model.  Its basically a large forgeworld dragon with all the problems associated with that.  The fit is generally good, but because I need to leave the wings off for painting I needed to spend some extra time on him.

This guy is huge... he doesn't fit on any of my shelves properly, so either the base is going to stick out, or I'm going to have to find somewhere else for him.  Looking forward to painting him, but am not sure how much time I'll have over the holidays (I'm also working on finishing my basement).

Let me know if you have any questions...
