Wasn't always super-happy about some of the details of this set so I set out to make some changes.  v1.5 includes all-new trees, color balance adjustments, various bugfixes and sample map bugfixes.  Some of the changes are significant, so if you don't like the new look, v1 is still available, inside the main zip file.

If you find any more bugs, don't hesitate to reach out to us!  We'll get them fixed asap.
