I reworked the Island, always in an attempt to reduce the file.
This Island is 2 miles by 2 miles (4 square miles) with a nice volcano at the center. Two large flat areas are there for you to build whatever you want. It is groups and componants, allowing you to move the water, or the land or the flat area, or to modify them as you desire.
I used color not textures to keep the file size down.
