I picked this up the day it came out and am in the process of building several pieces from it, so I may update this review as time goes on.
The first thing one can see about this is that while the previews show builds, they only give a sense of the complexity of the design that went into this product. The textures are amazing, the precision of the cuts is great, and the attention to detail, down to covering the side of the foamcore bases, is excellent.
The first few bases I built went together well. I noticed that even though I glued the base edging strip together so there was no overlap of color, I still had about a 1/4 inch gap when it was attached to the base. I will be experimenting with cutting the bases down ever so slightly, as this should fix the issue.
The tree stump bases are where I have found the most difficulty. Initially, I had not scored the big tab holding the 'body' together as there was no score line, but I realized soon that this distorts the shape of the trunk too much. After scoring, I was able to obtain a round shape but could not get it round enough; the walls seemed to have too much material. I broke it down and redid it, partially gluing to the base first to help hold the shape, and that worked well enough.
I have started assembling one hut, but have not done enough to comment on it yet.
The props are straight-forward and visially striking. These will be useful in many situation, not just a Swampworks build.
Overall, at this point, I would say this set is definitely not for beginners. Also, more than any other set I have built, cutting precision is vital. However, the finished result is one of the most visually striking and unique builds yet created by WWG.
