I want to start by saying that this model is impressive. With a base diameter of almost 12 inches and a height of 15 and 1/2 inches, it DOMINATES the tabletop. It is definitely a fine addition to your 3D terrain. Having said that I do have some problems with it.
This kit is not for novices. starting with the first level (there are 3), there were points that were, in my opinion, unclear. My experience with cardstock terrain models enabled me to figure out what the author meant but a newbie would be hard pressed. This problem just got worse with each subsequent level. It is like the author laid everything out clear and concise and then was told that he had to edit out parts to get the total number of bytes down to a certain limit. You clearly can't skimp on the graphics so they left out some steps in the instructions/illustrations. Perhaps they figured that if you followed the instructions laid out in level one, they didn't need to repeat themselves again in level 2 or 3. You would just "know" what to do. I found that very annoying and I am sure a newbie would end up confused.
The authors also suggested that you use double edged tape in some places stating that it made a great substitute for glue. I would go so far as to say double edged tape is MANDATORY in some areas. You can put it together without double edged tape (I did it after all), but double edged tape will save you a lot of time, aggravation, and frustration.
This is also a fairly complicated build. Three floors (2 of which have interiors) and other details. You will not complete it in an evening Being retired with more time than money, that was not a problem for me but be prepared to spend 2, or even 3 evenings working on this beauty.
