Nicely done! Haven't found any issues with any of the prefabs. Construction is nearly perfect and they are ready to be placed with no adjustments needed. One thing that Wonder Fox has done that so many vendors fail to do is to set proper height fading so that when you apply height it actually blends right in to it's surroundings instead of creating a large noticeable circle from the height differences. He also uses the proper spat application by not including grass/forest spats which I find can cause things to look unnatural when placing over existing blended splats. 

All in all a great bundle of prefabs for base builds. Worth the asking price. Hopefully there are more to come from Wonder Fox. 

Just purchased this today and tried out most of the prefabs on a custom map; the prefabs are very easy to place and work really well. The floating islands are stunning and the custom zipline is very easy to connect/use. My players are going to love these.
