whole island - again and again

The fact that I couldn't find the island file presented me with both a problem as it was in the last week and an opportunity to get it right especially getting the flat area for the runway, as is shown in the picture below. 

However, it went all wrong as I was only  viewing it from one angle - top view, so it didn't look particularly good.

So I started  again and this time I used a different technique.  I used the line tool to sketch out the islands and then extruded.  then I placed all the ships, trees and barrel in.

 

I was told to add some materials but I wasn't feeling well,  also the fact  that i wasn't feeling   well  made me miss the presentation that we  were supposed to give in week 12.

Due to bad communication between the members of the group I am unsure of which island they used for the final production.
